Asked by Mandy
A zinc-copper battery is constructed as follows at 25°C.
Zn|Zn^2+ (0.15 M)||Cu2+(3.00 M)|Cu
The mass of each electrode is 200. g.
a) Calculate the cell potential when this battery is first connected.
- i got this to be 1.14V
b.) Calculate the cell potential after 10.0 A of current has flowed for 10.0 h
(c) Calculate the mass of each electrode after 10.0 h.
d) How long can this battery deliver a current of 10.0 A before it goes dead?
please help! i just can't seem to figure out how to calculate the concentrations of the Zn^2+ and Cu^2+ after the current has flowed through.
-thanks.
