Find the total number of diprotic acids among the following:
`H_(3)PO_(4), H_(2)SO_(4), H_(3)PO_(3)`

Explanation

To find the total number of diprotic acids among the given compounds \( H_3PO_4 \), \( H_2SO_4 \), and \( H_3PO_3 \), we will analyze each compound to determine how many acidic protons (H⁺ ions) they can donate.

### Step-by-Step Solution:

1. **Identify the Compounds**: We have three acids to analyze:
- \( H_3PO_4 \) (Phosphoric acid)
- \( H_2SO_4 \) (Sulfuric acid)
- \( H_3PO_3 \) (Phosphorous acid)
