The net redox reaction of a galvanic cell is given below
`2 Cr (s) + 3 Cu^(2+) (aq) rarr 2 Cr^(3+) (aq) + 3 Cu (s)`
Write the half reactions and describe the cell using cell notation.

Explanation

Anodic oxidation `2Cr (s) rarr 2 Cr^(3+) (aq) + 6e^(-) ...... (1)`
Cathodic reduction : `3Cu^(2+) (aq) +6e^(-) rarr 3 Cu (s) ...... (2)`
Cell Notation is
`Cr (s) | Cr^(3+) (aq) || Cu^(2+) (aq) | Cu(s) `
