Mg(s) | Mg2+(0.001M) || Cu2+(0.0001 M) | Cu(s)
EoMg2+/Mg=-2.36 V; EoCu2+/Cu=0.34VEoMg2+/Mg=−2.36 V; EoCu2+/Cu=0.34V
The value of Ecell Ecell for the above reaction is -
1. | 3.46 V | 2. | 3.15 V |
3. | 2.67 V | 4. | 1.24 V |
Ecell=E⊝cell-0.0591nlog[Mg2+][Cu2+]
={0.34-(-2.36)}-0.05912log.001.0001
=2.7-0.05912log10
=2.7 - 0.02955
=2.67 V (approximately)
