An oxyacid contains three hydrogen atoms, one phosphorus atom and four oxygen atoms.
Name the different salts that can be formed by the acid on reaction with sodium hydroxide.

Explanation

To determine the different salts that can be formed from the oxyacid H₃PO₄ (phosphoric acid) when it reacts with sodium hydroxide (NaOH), we can follow these steps:

### Step 1: Identify the Oxyacid
The given oxyacid has three hydrogen atoms, one phosphorus atom, and four oxygen atoms, which corresponds to phosphoric acid (H₃PO₄).

### Step 2: Understand the Reaction
When an acid reacts with a base (in this case, NaOH), it undergoes a neutralization reaction that produces water and a salt. The general reaction can be represented as:
\[ \text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water} \]
