Options

A. Resistance
B. Potential
C. Concentration
D. Dissociation

Explanation

To solve the question regarding what the electrolytic conductance is a direct measure of, we will analyze the concepts involved step by step.

### Step-by-Step Solution:

1. **Understanding Electrolytic Conductance**:
- Electrolytic conductance refers to the ability of an electrolyte solution to conduct electric current. It is influenced by the presence of ions in the solution.

2. **Relation to Resistance**:
- Conductance (G) is the reciprocal of resistance (R). Therefore, if we know the resistance of the solution, we can determine its conductance using the formula:
\[ G = \frac{1}{R} \]
- This means that conductance is inversely related to resistance.

3. **Influence of Ion Concentration**:
- The conductance of an electrolyte solution increases with an increase in the concentration of ions. More ions in the solution lead to better conductivity because there are more charge carriers available to carry the electric current.

4. **Dissociation of Electrolytes**:
- When an electrolyte dissolves in a solvent, it dissociates into its constituent ions. The extent of this dissociation directly affects the number of ions available in the solution.
- Higher dissociation means more ions, which increases the conductance.

5. **Conclusion**:
- Therefore, electrolytic conductance is a direct measure of the concentration of ions in the solution, which is influenced by the degree of dissociation of the electrolyte.

### Final Answer:
The electrolytic conductance is a direct measure of the concentration of ions in the solution.
