    The questions consist of two atatements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses : Specifice conductiviy of an electrolytic solution decreases with dilution , whereas molar conductiviy increase with dilution . Specific conductivirty is the conductance of a specific amount of the electorolyte, whereas molar conductivity is for 1 mole of the electrolyte.

    Statement-1: Specific conductivity of an electrolytic solution decreases with dilution whereas molar conductivity. Statement-2: Specific conductivity is the conductance of a specific amount of the electrolyte whereas molar conductivity is for 1 mole of the electrolyte.

    Statement-1: Conductivity always decreases with decrease in concentration of both the weak and strong electrolytes. Statement-2: No. of ions per unit volume linearly decreases in both electrolytes.
