Concept: Balancing Redox Reactions: Acidic Solutions

# Problem: Balance the following redox reaction 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

Use the step-by-step process to determine the balanced redox reaction of each equation.

We are being asked to balance the given oxidation-reduction reaction. The reaction is under acidic conditionsWhen balancing redox reactions under acidic conditions, we will follow the following steps.

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

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

Step 3: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

Step 4: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
