Write the skeleton equation for each of the following processes and balance them by ion electron method :
(i) Permagnate ion oxidizes oxalate ions in acidic medium to carbon dioxide and gets reduced itself to `Mn^(2+)` ion .
(ii) Bromine and hydrogen peroxide react to give bromate ions and water .
(iii) Chlorine reacts with base to give chlorate ion, chloride ion and water.

Explanation

Let's solve the given problems step by step.

### (i) Permanganate ion oxidizes oxalate ions in acidic medium

**Step 1: Write the skeleton equation**
The skeleton equation for the reaction is:
\[ \text{MnO}_4^- + \text{C}_2\text{O}_4^{2-} \rightarrow \text{Mn}^{2+} + \text{CO}_2 \]
