Assertion and Reason:
Assertion: On increasing dilution, the specific conductance keeps on increasing.
Reason: On increasing dilution, the degree of ionisation of weak electrolyte increases and the molality of ions also increases.
Explanation:
The specific conductance of a solution is a measure of its ability to conduct electricity. It is directly related to the concentration of ions in the solution. When a weak electrolyte, such as acetic acid, is dissolved in water, it partially ionizes into ions. The degree of ionization is the extent to which the weak electrolyte dissociates into ions.
Effect of Dilution on Specific Conductance:
When a solution is diluted, the concentration of the ions decreases. However, the volume of the solution increases. As a result, the total number of ions remains constant. Therefore, the specific conductance of the solution increases with increasing dilution.
Reasoning behind the Assertion and Reason:
The Assertion states that on increasing dilution, the specific conductance keeps on increasing. This is true because the dilution of a solution leads to a decrease in the concentration of ions, resulting in an increase in the specific conductance.
The Reason states that on increasing dilution, the degree of ionisation of weak electrolyte increases and the molality of ions also increases. This is incorrect because the degree of ionization of a weak electrolyte does not increase with dilution. In fact, the degree of ionization decreases with dilution due to the decrease in concentration. The molality of ions also does not increase with dilution, as the total number of ions remains constant.
Conclusion:
Based on the explanation above, it can be concluded that both the Assertion and Reason are incorrect. The specific conductance of a solution increases with increasing dilution, but the reason provided for this is not correct. The degree of ionization of a weak electrolyte decreases with dilution, and the molality of ions does not increase with dilution. Therefore, option 'D' is the correct answer.
