Directions: In the following questions, A statement of Assertion (A) ...
Assertion: Conductivity of an electrolyte increases with decrease in concentration.
Reason: Number of ions per unit volume decreases on dilution.
The correct answer is option D, which means that Assertion A is false and Reason R is true.
Explanation:
- Conductivity of an electrolyte is a measure of its ability to conduct electric current. It depends on the presence of ions in the solution.
- When an electrolyte dissolves in a solvent, it dissociates into positive and negative ions. These ions are responsible for carrying electric charge through the solution.
- The concentration of an electrolyte refers to the amount of solute (electrolyte) dissolved in a given amount of solvent (usually expressed in moles per liter).
- Assertion A states that the conductivity of an electrolyte increases with a decrease in concentration. This is not true. In fact, the conductivity of an electrolyte generally decreases with a decrease in concentration.
- Reason R states that the number of ions per unit volume decreases on dilution. This is true. When an electrolyte solution is diluted, the overall volume of the solution increases while the amount of solute remains the same. As a result, the concentration of the electrolyte decreases. Since conductivity depends on the presence of ions, a decrease in concentration leads to a decrease in the number of ions per unit volume, resulting in a decrease in conductivity.
Conclusion:
- The assertion that conductivity of an electrolyte increases with a decrease in concentration is false.
- The reason that the number of ions per unit volume decreases on dilution is true.
- Therefore, option D is the correct answer.
Reason: Number of ions per unit volume decreases on dilution.
The correct answer is option D, which means that Assertion A is false and Reason R is true.
