Text Solution

AI Generated Solution

### Step-by-Step Text Solution 1. **Identify the Reactants**: The reaction involves potassium dichromate (K₂Cr₂O₇) which is acidified with sulfuric acid (H₂SO₄). The reducing agent in this case is sulfur dioxide (SO₂). 2. **Write the Reaction**: The overall reaction can be represented as: \[ K_2Cr_2O_7 + H_2SO_4 + SO_2 \rightarrow Cr_2(SO_4)_3 + H_2O \] ...
