Question

When a solution of sodium hydroxide is added to acetic acid solution, the conductivity of the resulting solution will

• A. increase
• B. remain unchanged
• C. decrease
• D. become zero

Answer 1

Answer: (A)

increase

Answer 2

Increase because $NaOH$ is strong base and $CH _{3} COOH$ is weak acid, when mixed then the salt formation takes place, i.e., $CH _{3} COONa$. Salt increases the conductivity.
