Experimental
Data Analysis
Investigation
of various solutions.
The subject of the study was solutions of different alkali:
KCl, NaCl, KNO3, NaNO3 in deionised distilled water at different
concentrations. For each concentration 30-40 measurements
were carried out (except for KCl). Investigating various concentrations
of solutions from normal to 16000th dilution, which correspond
to the range from 101,1 to 0,00357 (gram*mole), the data analysis
disclosed the following regularities.
At
the level of second dilution (approximately 0.5 (gram*ecv)/litre)
fractality coefficient decreases relatively to its normal
value, and then, at the level of the fourth (0.27 (gram*ecv)/litre),
goes up. Further, having some small differences which statistics
is shown in Tables 3.5-3.16, it falls to the level of 256th
dilution (0,004 (gram*ecv)/litre). At the level of 512th dilution
(0,00197 (gram*ecv)/litre) it grows again, and starting from
the level of 1024th dilution (0,00987 (gram*mole)/litre) goes
down stable till the 16384th dilution (0,0000617 (gram*mole)/litre),
at which level the statistically significant differences between
solutions and water disappear (Tables 3.5-3.16 and Fig. 3.5-3.8).
It
is remarkable that no other method was sensitive to the indicated
"anomalies" at the level of the second and 512th
dilution. The explanation should apparently consist in peculiar
interstructuring of solutions in the given dilutions. At present
the physico-chemical interpretation of this phenomenon is
well underway.
In
spite of a certain conformity of general behavior of electrolytes
and some statistically indistinguishable points, on the whole,
the difference of each concentration line from all the others
is statistically significant. The general picture of the sensitivity
(planned at about 60%) shows that the sensitivity is lower
than it was planned, which fact results from a small difference
of the average values and from the quantity of samples not
more than 40. This problem could be solved by a further optimisation
of experiment, for example, using two or more experimental
setups simultaneously, which would enable to decide the issue
of quantity of samples received under the same conditions.
Now
let us pass over to the analysis of dependence of such parameters
as illumination area, entropy, and autocorrelation angle,
upon concentration degree using the example of NaNO 3. The
corresponding data and diagrams are given in Tables 3.7, 3.10-3.12
and Fig. 3.5-3.8. Data for KNO3 are given in tables 3.6, 3.14,
3.15; for NaCl in Tables 3.9, 3.13, 3.14; for KCl in Table
3.8. Comparison of averaged data for all the solutions are
given in Table 3.5. and at fig.3.8. From these data it is
clearly seen statistical difference between different alkali
solutions, but as demonstrate fig.3.8, this difference is
not monotonous for all concentrations.
Data
on the respective parameters of distilled water is presented
in Table 3.16, which makes it obvious the statistical difference
between water and alkali solutions and prove the fact that
analysing the type of fractal parameter distribution for water
and solutions we deal with normal distribution for the stated
above reasons.
Fig.
3.8 demonstrate that a "curvature" remains at the
second dilution and a "curvature" appears at 256th
dilution (approximately 0,395 (gram*mole)/litre), preceding
the "curvature" mentioned before at 512th dilution
(approximately 0,197 (gram*mole)/litre), fractal coefficient
depending upon the concentration degree. Same curvatures may
be seen at the other parameters (Fig.3.5-3.7). This proves
that these curvatures correlate with some properties of the
solutions and should be treated from the basic positions.
The
given number of measurements is necessary to provide above
60% sensitivity of the experiment.
The given solutions were different in ion radiuses (Table
3.14) and electroconductivity (equivalent electroconductivity
for various concentrations is represented in Table 33.14 and
Fig.3.5, 3.6), but were similar, being strong electrolytes
and being able to dissociate completely into ions by the solvent.
During
the given research the following parameters were considered:
Fractality coefficient, Entropy, Area and Autocorrelation
angle.
Fractality
coefficient is peculiar due to the following empiric assumptions.
Fractality of GDV-grams of solutions must probably reflect
flexibility and activity of ions in the given solution. With
the lower concentration of solutions ions move apart so that
their interaction decreases and reflection of the processes
in solutions on GDV-grams under the influence of electromagnetic
field is getting more systematic. This dependency on the properties
and concentration of ions is similar to the dependency of
equivalent electroconductivity of solutions, which is of great
physical-mathematical and diagnostic value. Thus, the task
to reveal the relation between Fractality coefficient and
equivalent electroconductivity is actual.
Entropy
is the measure of deviation from the balance: it decreases
with reaching the balance. From this point, its dynamics during
dilution is interesting.
Autocorrelation
function characterizes regularity of the process. If autocorrelation
from some distance r equals zero, there are no correlations
at the distance r. The study of biological objects of different
nature demonstrates that this parameter has a great practical
meaning. Autocorrelation dynamics during dilution is also
interesting.
The
glow area of drops of the same size is the function of photon
emission from their surface. Consequently, activity and flexibility
of ions as well as ionization and dissociation degree will
contribute to the value of the given parameter. This suggestions
allows assumption on the connection between glow area and
equivalent electroconductivity.
Lets
consider all the studied parameters.
Despite some similarity in the general behavior of electrolytes
and some statistically significant points, each line of concentration,
in general, statistically differs from the others. This can
be observed in the dispersion analysis represented in the
table 3.22. However, dispersion analysis allows to check out
only the hypothesis on the equality of all the average values.
But, if the hypothesis is not confirmed, there is no possibility
to find out which group is different from the others. This
can be done, applying the methods of comparison based on the
Student's criteria, such as Bonferrony's remark, Newman-Kales
criteria and etc. Comparing two points of different concentrations
of one solution or two points with similar concentration of
different solutions one can apply Student's t-criteria. The
examples of this comparisons are represented in Table 3.19
- 3.21.
Basing
on the described data the graphs of dependency of Fractality
coefficient on the equivalent electroconductivity were built
(Fig. 3.25 - 3.28). The analysis demonstrated that the given
dependency can be approximated applying the method of the
smallest squares of polynomial curve of the third range. Equations,
describing this approximate values and coefficients of multiple
correlation (CMC) are marked on the graphs. The given CMC
values indicate high reliability of such approximation. X
indicates the normalized according to the equivalent electroconductivity
which equals 1cm2/ (Ohm g-eqv). Coefficients in polynomials
are probably connected with the size of ions of corresponding
anions and cations. Diminution of values of the given coefficients
corresponds to the decrease of values of ion radiuses. Physical-chemical
interpretation and mathematical model of the given dependency
in the nearest future will be activity developed.
Lets
analyze the dependency of Entropy on the concentration of
solutions. Corresponding data and graphs are represented in
the Table 3.23 - 3.26 and Fig. 3.29 - 3.30. The data on the
corresponding distilled water parameters are represented in
the Table 3.8.
Fig.
3.29 - 3.30 demonstrates, that the "gap" in the
second dilution is preserved and reveals a "gap"
on the level 0.00195 (g-eqv)\L depending on Fractality coefficient
and concentration degree. This can be interpreted according
to the definition, characterizing entropy as the increase
of deflection from the balance unstable in dynamics of entropy
diminution with the lower concentration of solutions.
According
to the data obtained and figures, it is obvious that there
is no statistically significant differences between points,
corresponding to entropies of diverse solutions in consequence
of entropy, which, in the given case, corresponds not to the
differences in sizes of ions and electroconductivity, but
to the degree of dissociation which is lower among the investigated
electrolytes.
The
data of the analysis of Autocorrelation function is given
in Table 3.27 - 3.30 and Figure 3.31 - 3.32. Autocorrelation
function as a measure of the process regularity is revealed,
as expected, according to the chemical properties of solutions
of strong electrolytes, analogous for all the solutions. Concentration
of 0,125 (g-eqv)\L for KC1 is the exception. The difference
for this concentration in comparison to the other points is
statistically important. The explanation of the given phenomena
should be found in the solubility of the given electrolyte.
The
analysis of dependencies of Autocorrelation function and Entropy
on the equivalent conductivity, corresponding to various concentrations
of solutions (fig. 3.38 - 3.45) revealed no adequate and highly
reliable approximate values with the similar degree of polynomial,
like in the case with Fractality coefficient, having, obviously,
the same model of approximation for all concentrations of
the investigated strong electrolytes.
The
results of the analysis of area, represented in Table 3.31
- 3.33 and Fig. 3.33 - 3.34 demonstrate similar behavior in
dynamics of curves of solutions and, at the same time, statistically
significant differences in the majority of concentrations.
According to the data described, the graphs of the area dependency
from equivalent electroconductivity were built (Fig. 3.35
- 3.37). The analysis demonstrated that the given dependency
can be approximated by the polynomial curve of the fifth range.
Equations relating to these approximations are given in the
graphs. Just as in the case with Fractality coefficient the
coefficients values of multiple correlation reveal high reliability
of such approximation.
According
to the data, it is evident that on the level of dilution 0.000061
(g-eqv)\L the solution still has statistically significant
differences from water, revealed in three parameters - Area,
Entropy and Autocorrelation angle.
Thus,
the data obtained demonstrate that these three parameters
are more sensitive than Fractality coefficient when comparing
solutions with water,. According to sensitivity they are ranged
as follows: Area, Entropy, Autocorrelation angle. However,
Fractality coefficient is significant due to the high sensitivity
when revealing such differences in solutions as ion radiuses
and elctroconductivity.
However,
experimental data show that the 16000th dilution (about 0,00357
(gram*mole)/litre) still has statistically significant differences
from water by all the parameters - illumination area, entropy,
fractal parameter and autocorrelation angle. Thus, the data
received indicates that all these parameters are sensitive
for comparison solutions and water. Nevertheless, all the
parameters are valuable for the fact that their comparison
gives an opportunity to observe different details of solutions
behaviour, that is important for analysing of the interstructuring
of solutions (512th dilution). All data received contribute
for the fact that GDV Technique is much more sensitive than
the other well-known methods of revealing differences according
to various parameters, which, as a rule, become insignificant
at the level of 2000th dilution already.
