Answer the following in brief.
Explain the effect of dilution of the solution on conductivity?
- The electrolytic conductivity is the electrical conductance of unit volume (1 cm3) of solution. It depends on the number of current-carrying ions present in unit volume of solution.
- On dilution total number of ions increases as a result of an increased degree of dissociation.
- An increase in the total number of ions is not in the proportion of dilution. Therefore, the number of ions per unit volume of solution decreases.
- This results in a decrease of conductivity with a decrease in the concentration of the solution.
Concept: Electrical Conductance of Solution
