Assertion: On dilution, the equivalent as well as molar conductivity of the solution increases. Reason: With dilution, the number of current carrying particles per cm^(3) increases.

Answer»

If both ASSERTION and reason are true, and reason is the true explanation of the assertion
if both assertion and reason are true, but reason is not the true explanation of the assertion.
if assertion is true, but reason is false.
If both assertion and reason are false.

Solution :Correct R. on diluton, the number of current carrying particles PER `cm^(3)` decreases and hence specific conductivity decreases. `wedge_(EQ) and wedge_(m)` increase with dilution because `wedge_(eq)=` sp. Conductivity `XX` volume of solution containing 1 g eq. of the electrolyte and `wedge_(m)=`sp. conductivity`xx`volume of solution containing 1 mole of th electrolyte and volume increases much more than decrease in specific conductivity.
