Complete and balance the following in acidic medium:
`Ag^(o+)+AsH_(3)rarrH_(3)AsO_(3)`

Explanation

To complete and balance the given redox reaction in acidic medium, we will follow these steps:

### Step 1: Identify the oxidation and reduction half-reactions
In the reaction, we have:
- Silver ion \( \text{Ag}^+ \) is being reduced to metallic silver \( \text{Ag} \).
- Arsenic in \( \text{AsH}_3 \) is being oxidized from an oxidation state of -3 to +3 in \( \text{H}_3\text{AsO}_3 \).

### Step 2: Write the half-reactions
