FREE Expert Solution

When writing a cell notation, we use the following format – “as easy as ABC

Hence, the Cu/Cu+2 is the anode reaction while Ag+/Ag is the cathode reaction


(1) Calculating E°cell


E°cell=E°cathode-E°anode


E°cell = 0.08 – (0.34)

cell = +0.46 V


(2) Calculating Ecell using Nernst equation:

Ecell = E°cell-0.05912log[Cu+2][Ag+]2Ecell = 0.46-0.05912log0.015(2.5)2

Ecell = +0.53 V
