What is the basicity of `H_(3)PO_(3)` ?

Explanation

To determine the basicity of \( H_3PO_3 \), we can follow these steps:

### Step 1: Understand Basicity
Basicity refers to the number of hydrogen ions (H⁺) that an acid can donate. For a given acid, the basicity can be determined by counting the number of ionizable hydrogen atoms.

### Step 2: Analyze the Structure of \( H_3PO_3 \)
The molecular formula \( H_3PO_3 \) indicates that it contains three hydrogen atoms. To understand the basicity, we need to consider how many of these hydrogen atoms can dissociate as H⁺ ions.
