# Problem: Balance each of the following redox reactions occurring in acidic solution. Express your answer as a chemical equation. Identify all of the phases in your answer.Cr2O72?(aq)+Cu+(aq)?Cr3+(aq)+Cu2+(aq)

###### FREE Expert Solution

To balance the given oxidation-reduction reaction:

Cr2O72-(aq) + Cu+(aq)  → Cr3+(aq) + Cu2+(aq)

Step 1: Separate the whole reaction into two half-reactions:

Cr2O72-(aq)  Cr3+ (aq)                      Cu+(aq→ Cu2+(aq)

Step 2: Balance the non-hydrogen and non-oxygen elements first:

Cr2O72-(aq)  2Cr3+ (aq)                    Cu+(aq→ Cu2+(aq)

(Cr: balanced)                                               (Cu: balanced)
