Question 22
H

A student measures the voltage of a cell made from a zinc electrode and a copper electrode. The student then replaces the copper electrode with a silver electrode. Silver is less reactive than copper. What happens to the voltage of the cell, and why?

[1]
A

It decreases, because the difference in reactivity of the electrodes decreases

B

It decreases, because the difference in reactivity of the electrodes increases

C

It increases, because the difference in reactivity of the electrodes decreases

D

It increases, because the difference in reactivity of the electrodes increases
