State true or false
Boric acid is prepared from borax by the action of HCl

Answer

To determine whether the statement "Boric acid is prepared from borax by the action of HCl" is true or false, we can follow these steps:

### Step 1: Identify the Compounds
- **Boric Acid**: The chemical formula for boric acid is H₃BO₃.
- **Borax**: The chemical formula for borax is Na₂B₄O₇.

### Step 2: Write the Reaction
When borax (Na₂B₄O₇) reacts with hydrochloric acid (HCl) in the presence of water, the following reaction occurs:
\[ \text{Na}_2\text{B}_4\text{O}_7 + \text{HCl} + \text{H}_2\text{O} \rightarrow \text{H}_3\text{BO}_3 + \text{NaCl} \]

### Step 3: Balance the Reaction
To balance the reaction, we can express it as:
\[ \text{Na}_2\text{B}_4\text{O}_7 + 6 \text{HCl} + 5 \text{H}_2\text{O} \rightarrow 4 \text{H}_3\text{BO}_3 + 2 \text{NaCl} \]
This shows that boric acid is indeed produced when borax reacts with hydrochloric acid.

### Step 4: Conclusion
Since the reaction confirms that boric acid (H₃BO₃) is produced from borax (Na₂B₄O₇) by the action of hydrochloric acid (HCl), we can conclude that the statement is **True**.

### Final Answer
**True**
