Description

1. Using data on the properties of solutions of substance A in water:
1) plot the dependence of the specific and equivalent electrical conductivity of solutions of substance A on dilution V;
2) check whether the solutions of substance A in water obey the Ostwald dilution law;
3) Calculate for substance A, using the given dependences of equivalent electrical conductivity on concentration, the equivalent electrical conductivity at infinite dilution and compare the result with the reference data.
