It is known that for high concentration of , reduction will take place. As, cathode has a positive charge and it will be placed on left hand side.
Now, = 0 and the general reaction equation is as follows.
3.00 M n = 2 30 mM
E =
=
= 0.038 V
Therefore, we can conclude that voltage shown by the voltmeter is 0.038 V.
