To balance the given redox reaction in acidic medium, we will follow a systematic approach. Here are the steps involved: ### Step 1: Write the Unbalanced Equation We start with the skeletal equation of the reaction: \[ \text{Cr}_2\text{O}_7^{2-} (aq) + \text{SO}_3^{2-} (aq) \rightarrow \text{Cr}^{3+} (aq) + \text{SO}_4^{2-} (aq) \] ### Step 2: Separate into Half Reactions Identify the oxidation and reduction half-reactions: ...
