Statement-1 : The ratio of specific conductivity to the observed condu...
Statement-1: The ratio of specific conductivity to the observed conductance does not depend upon the concentration of the solution taken in the conductivity cell.
Statement-2: Specific conductivity decreases with dilution whereas observed conductance increases with dilution.
Explanation:
To understand the relationship between specific conductivity, observed conductance, and concentration, let's first define these terms:
- Specific conductivity: It is the conductivity of a solution divided by the product of the conductivity of the solvent and the concentration of the solution. It represents the conductivity per unit concentration.
- Observed conductance: It is the actual conductance measured in a conductivity cell, which depends on the conductivity of the solution and the geometry of the cell.
Now let's analyze the given statements:
Statement-1: The ratio of specific conductivity to the observed conductance does not depend upon the concentration of the solution taken in the conductivity cell.
This statement is true. The specific conductivity is defined as the ratio of conductivity to concentration, while observed conductance is the actual conductance measured in a cell. The ratio of specific conductivity to observed conductance is independent of concentration because the concentration cancels out in the division. Therefore, this statement is true.
Statement-2: Specific conductivity decreases with dilution whereas observed conductance increases with dilution.
This statement is also true. When a solution is diluted, the concentration of ions decreases, leading to a decrease in specific conductivity. This is because there are fewer ions available to carry the electric current. On the other hand, observed conductance increases with dilution because the conductivity cell measures the total conductance of the solution, which includes both the conductance of the solvent and the conductance of the solute. As the volume of solvent increases during dilution, the conductance of the solvent contributes more to the observed conductance, resulting in an overall increase.
Explanation of the Correct Answer:
The correct answer is option 'B': Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1.
Statement-2 provides a correct explanation for the trend observed in specific conductivity and observed conductance with dilution. However, it does not explain why the ratio of specific conductivity to observed conductance is independent of concentration. The independence of this ratio on concentration is due to the mathematical definition of specific conductivity, where the concentration term cancels out. Therefore, while both statements are individually true, the second statement does not provide a correct explanation for the first statement.
