Question 7
H

A student makes a cell using two iron electrodes in a solution of sodium chloride. Which voltage will the student measure, and why?

[1]
A

0.34 V0.34\ \text{V}0.34 V, because iron is more reactive than sodium is

B

0.76 V0.76\ \text{V}0.76 V, because iron is less reactive than sodium is

C

0.00 V0.00\ \text{V}0.00 V, because both of the electrodes are the same metal

D

1.10 V1.10\ \text{V}1.10 V, because the electrolyte contains chloride ions
