Assertion: On increasing dilution, the specific conductance keeps on increasing.
Reason: On increasing dilution, the degree of ionisation of weak electrolyte increases and molality of ions also increases.
Correct answer: Option 'D' - If both the Assertion and Reason are incorrect.
Explanation:
The given assertion and reason state that on increasing dilution, the specific conductance keeps on increasing. However, this statement is incorrect.
Specific conductance:
Specific conductance is a measure of how well a solution conducts electricity. It is defined as the reciprocal of resistivity and is denoted by the symbol κ (kappa). The unit of specific conductance is Siemens per meter (S/m).
Effect of dilution on specific conductance:
When a solution is diluted, the concentration of ions in the solution decreases. As a result, the number of ions available for the conduction of electricity decreases. Therefore, on increasing dilution, the specific conductance of a solution decreases.
Explanation of the reason:
The reason given for the assertion is that on increasing dilution, the degree of ionisation of weak electrolyte increases and the molality of ions also increases. However, this reason is incorrect.
Degree of ionisation:
The degree of ionisation of a weak electrolyte is the fraction of the molecules that dissociate into ions in a solution. It is determined by the equilibrium constant (Ka) of the dissociation reaction. The degree of ionisation of a weak electrolyte decreases with increasing dilution, as the concentration of the electrolyte decreases.
Molality of ions:
Molality is a measure of the concentration of ions in a solution and is defined as the number of moles of solute per kilogram of solvent. When a solution is diluted, the molality of ions decreases because the concentration of the solute decreases.
Therefore, the reason given for the assertion is incorrect, as increasing dilution does not lead to an increase in the degree of ionisation of a weak electrolyte or the molality of ions. Hence, the correct answer is option 'D' - If both the Assertion and Reason are incorrect.
Reason: On increasing dilution, the degree of ionisation of weak electrolyte increases and molality of ions also increases.
Correct answer: Option 'D' - If both the Assertion and Reason are incorrect.
