Problem: Complete and balance the following half-reactions. In each case indicate whether the half-reaction is an oxidation or a reduction.Complete and balance the following half-reaction: Mo3+(aq)  →  Mo(s)  (acidic  solution)

FREE Expert Solution

We’re being asked to balance the given half-reaction and indicate whether it is an oxidation or reduction reaction.


 Mo3+(aq)  → Mo(s)  (acidic  solution)


When balancing redox reactions under acidic conditions, we will follow the following steps.

Step 1: Balance the non-hydrogen and non-oxygen elements first.

Step 2: Balance oxygen by adding H2O to the side that needs oxygen. (1 O: 1 H2O)

Step 3: Balance hydrogen by adding H+ to the side that needs hydrogen. (1 H: 1 H+)
