Balance the following equations:
i. `As_(2)S_(3)+NaClO_(3)+NaOHrarrNa_(3)AsO_(4)+NaClO+Na_(2)SO_(4)`

Explanation

To balance the given redox reaction, we will follow a systematic approach. The reaction is:

\[ \text{As}_2\text{S}_3 + \text{NaClO}_3 + \text{NaOH} \rightarrow \text{Na}_3\text{AsO}_4 + \text{NaClO} + \text{Na}_2\text{SO}_4 \]

### Step 1: Write the unbalanced equation
The first step is to clearly write down the unbalanced equation:

\[ \text{As}_2\text{S}_3 + \text{NaClO}_3 + \text{NaOH} \rightarrow \text{Na}_3\text{AsO}_4 + \text{NaClO} + \text{Na}_2\text{SO}_4 \]
