Problem: Complete and balance the following equations, and identify the oxidizing and reducing agents.Part ACr2O72−(aq) + I −(aq) → Cr 3+(aq) + IO3−(aq) (acidic solution)Express your answer as a chemical equation. Identify all of the phases in your answer.Part Boxidizing agent, reducing agentExpress your answers as chemical expressions separated by a comma.

• Balance the redox reaction and determine the oxidizing/reducing agent in each reaction.
• Recall that the oxidizing agent is the one being reduced (GER-OA = Gain electrons, reduced- Oxidizing agent) while reducing agent is the one being oxidized (LEO-RA = Lose electrons, oxidized – Reducing agent)

PART A

We are being asked to balance the given oxidation-reduction reaction. The reaction is under acidic conditions. Balance the redox reaction under acidic conditions:

Cr₂O₇²⁻(aq) + I⁻ (aq) → Cr ³⁺(aq) + IO₃⁻(aq)
