When a solution of an electrolyte is heated the conductance of the solution

Options

A. Increases because of the electrolyte conducts better
B. Decreases because of the increased heat
C. Decreases because of the dissociation of the electrolyte is suppressed
D. Increases because the electrolyte is dissociated more

Explanation

### Step-by-Step Solution:

1. **Understanding Conductance**: Conductance is the ability of a solution to conduct electricity, which depends on the presence of ions in the solution. The more ions present, the higher the conductance.

2. **Effect of Heating on Electrolytes**: When an electrolyte solution is heated, the temperature increase can affect the degree of dissociation of the electrolyte.

3. **Degree of Dissociation**: The degree of dissociation refers to the extent to which an electrolyte separates into its constituent ions in solution. For weak electrolytes, increasing temperature typically increases the degree of dissociation.

4. **Impact on Conductance**: As the degree of dissociation increases with temperature, more ions are produced in the solution. This increase in the number of ions leads to an increase in the solution's conductance.

5. **Conclusion**: Therefore, when a solution of an electrolyte is heated, the conductance of the solution increases because the electrolyte dissociates more, resulting in a higher concentration of ions available to conduct electricity.

### Final Answer:
The conductance of the solution increases because the electrolyte conducts better due to an increase in the degree of dissociation.
