Statement-I: The voltage of mercury cell remains constant for long period of time.

Statement - II: The net cell reaction does not involve active species(ions) .

View answer and explanation

Correct option: A

Both Statements-I and II are correct and Statement - II is correct explanation for Statement - I.

Option A is correct because the voltage of a mercury cell remains constant due to the net cell reaction not involving ions in solution, which means the concentration of the active species remains constant.
