Question

Divide the following redox reactions into oxidation and reduction half reactions.
Zn + $C u^{2} +$ → $Z n^{2} +$ + Cu

Open in App

Solution

The redox reactions into oxidation and reduction half reactions:-

Oxidation half reaction:

Zn → $Z n^{2} +$ + 2e- (Loss of two electrons)

Reduction half reaction:

$C u^{2} +$ + 2e-→ Cu (Gain of two electrons)
