Question

Use the following steps to balance the redox reaction below:

Answer 1

Answer:

(a)

Oxidation

Na -> Na+  +  e

Reduction

Cu2+   + 2e -> Cu

(b) Just multiply oxidation half-reaction by 2 and reduction half-reaction by 1.

2Na -> 2Na+  + 2e

Cu2+  + 2e -> Cu

(c) 2Na + Cu2+ -> 2Na+  +  Cu (2e cancels each other)

Please be reminded, this answer may not be correct.
