Write a balanced overall reaction from these unbalanced half-reactions. ln->ln3 + cd2+->cd

Oxidation reaction

In - - - > In³⁺ + 3e - - - 1)

reduction reaction

Cd²⁺ + 2e - - - > Cd - - - 2)

when balancing the reactions, electrons have to be balanced. to balance the electrons multiple 1st reaction by 2 and 2nd reaction by 3

1) x 2

2) x 3

2In - - - > 2In³⁺ + 6e

3Cd²⁺ + 6e - - - > 3Cd

add the 2 equations to obtain the overall reaction

2In + 3Cd²⁺ - - - > 2In³⁺ + 3Cd
