Supply a balanced chemical equation for the reaction of permanganate with the hydrogen sulfite in a basic solution?

### Oxidation of Aromatic Compounds

**Introduction**

The oxidizing agents that can be used are chromic acid (using Na2Cr2O7 or CrO3 in sulfuric acid and water) or potassium permanganate (KMnO4). The product in each case is benzoic acid or a derivative of benzoic acid. The permanganate reaction requires the addition of acid since it generates a basic solution as a byproduct.

**Reaction Pathways**

1. **Oxidation with Potassium Permanganate and Acid:**
   - **Reactant:** Aromatic methyl group (represented as CH3)
   - **Oxidizing Agent:** KMnO4, H2O, Δ (heat)
   - **Acid Workup:** H3O+, H2O
   - **Product:** Benzoic acid derivative (e.g., carboxylic acid group attached to benzene ring)

2. **Oxidation with Chromic Acid:**
   - **Reactant:** Aromatic methyl group (attached to a nitro group, NO2)
   - **Oxidizing Agent:** CrO3, H2SO4, H2O
   - **Heat Required**
   - **Product:** Benzoic acid derivative

**Experimental Focus:**

In this experiment, potassium permanganate is used to oxidize 2-chlorotoluene (o-chlorotoluene) to 2-chlorobenzoic acid (o-chlorobenzoic acid). Permanganate solutions are less hazardous compared to those containing chromium compounds, which are often carcinogenic.

- **Reaction Overview:**
  - **Reactant:** 2-Chlorotoluene
  - **Oxidizing Agent:** KMnO4, H2O, Δ
  - **Acid Workup:** HCl, H2O
  - **Product:** 2-Chlorobenzoic acid

**Yield Information:**
The reaction yield observed in the literature is between 76-78% before recrystallization and 65-67% after recrystallization (Clarke, H. T.; Taylor, E. R. Org. Synth. 1930, 10, 20).

**Procedure**

**Safety:**
- **Potassium Permanganate:** Strong oxidizer, corrosive. Wear gloves to handle.
- **2-Chlorotolu
