Cu no3 2 + zn
WebZn (s) + Cu 2+ (aq) → Cu (s) + Zn 2+ (aq) Although this reaction is already balanced, it is instructive to see the process applied: 1) Zn has 0 charge, Zn 2+ has 2+ charge, it is oxidized; Cu 2+ has 2+ charge, Cu has 0 charge, it is reduced. 2) The half reactions are: Ox: Zn (s) → Zn 2+ (aq) + 2 e - Red: Cu 2+ (aq) + 2 e - → Cu (s) WebChoose Zn(NO 3) 2 (aq) as the solution when metal Zn is chosen. Make sure you arrange the metals appropriately to get a positive reading on the voltmeter. Voltaic Cell C: Cu, Zn …
