Product description
- Using data on the properties of solutions of substance A in water:
- build graphs of the dependence of the specific and equivalent electrical conductivity of solutions of substance A on dilution V;
- check whether the solutions of substance A in water obey the Ostwald dilution law;
- Calculate for substance A, according to the dependence of equivalent electrical conductivity on concentration, the equivalent electrical conductivity at infinite dilution and compare the result with the reference data.
Dependence of the resistance r of a solution of substance A on the concentration c at 298 K:
