Redox reactions?

Question

The following electrochemical (galvanic) cell is constructed as given by the line notation:

Zn(s) | Zn2+(aq),1M || Cu2+(aq),1M | Cu(s)

(If you do not know what the line notation means, read about in the lab manual and/or text)

The Ecell measured for this cell is 1.10 V. Note that the concentrations of Zn2+(aq) and Cu2+(aq) are both 1M (standard conditions). Will the value of Ecell increase, decrease, or remain the same if the amount of Zn(s) metal in the anode is increased?

Answer 1

The value of Ecell remains the same if the amount of Zn metal is increased. The only effect of a larger anode is that the cell may last longer.
