Which of the following statement is correct?
1 Conductivity of a solution increases with dilution, whereas molar conductivity decreases with dilution.
2 Conductivity of a solution decreases with dilution, whereas molar conductivity increases with dilution.
3 Both conductivity and molar conductivity increase with dilution.
4 Both conductivity and molar conductivity decrease with dilution.
Explanation:
Conductivity of a solution decreases with dilution due to decrease in number of ions per unit volume, whereas molar conductivity increases with dilution due to decrease in molarity.

An increases in equivalent conductivity of strong electrolyte with dilution is mainly due to
1 Increases in both, i.e., number of ions and ionic mobility
2 Increases in number of ions
3 Increase in ionic molility of ions
4 ionisation of electrolyte at normal dilution
Explanation:
On dilution, normality decreases, number of charge carriers per decreases but the volume increases. Consequently, the ionic mobility increases, which increase equivalent conductance.

The conductivity of an electrolytic solution decreases on dilution due to
1 decrease in number of ions per unit volume
2 increase in ionic mobility of ions
3 increase in percentage ionisation
4 increase in number of ions per unit volume
Explanation:
Conductivity always decreases with increase in dilution of both the strong and weak electrolytes. This is due to the fact that the number of ions that carry current in a volume of solution always decreases upon dilution.

Assertion : On dilution, the equivalent as well as molar conductivity of solution increases. Reason : With dilution, the number of current carrying particles per increases.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
On dilution, the interionic attractions decreases, so dissociation increases. Thus, equivalent as well as molar conductivities increases. This is because the total volume of a solution containing equivalent or 1 mole of electrolyte also increases. However, the number of current carrying particles per decreases on diluting the solution. Hence, Assertion is correct but Reason is incorrect.
