Abstract

The relation between the electrical conductivity (Λ) and the Ionic strength (I) of strong bi-charge electrolytes like
(sodium soleplate and potassium soleplate) were studied over range of concentrations (from 0.01 to 1.00)mol. The
electrical conductivity of such ions measured then the ionic strength calculated.
A new mathematical formula deduced from this experimental results, which is:
I=F* Λ
Where is F, the proportional factor.
This equation can give the ionic strength directly over a limited range of concentrations with high accuracy and short
time.
The ionic strength of solutions formed of two components with common negative ion was studied. A tremendous
decrease of the conductivity occurred independently from increasing the ionic strength, compared with those calculated
from using the general law of the electrical conductivity of electrolytes: = å 1
2
2 1
I 1 Z C This phenomenon attributed
to the effect of doubly charged common ion of the salt and the relaxation effect of the solvent.
The calculated ionic strength based on this suggested experimental mathematical equation was in good agreement with
those calculated by using Deby-Huckel law.
