When mango is placed in dilute aqueous solution of hydrochloric acid, it swells (T/F)

Explanation

To determine whether the statement "When mango is placed in dilute aqueous solution of hydrochloric acid, it swells" is true or false, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Solution**:
- A dilute aqueous solution of hydrochloric acid (HCl) is primarily composed of water and a small concentration of HCl.

2. **Osmosis Concept**:
- Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

3. **Comparing Concentrations**:
- The inside of the mango contains a higher concentration of solutes (like sugars and other cellular components) compared to the dilute HCl solution outside. Therefore, the HCl solution is hypotonic relative to the interior of the mango.

4. **Water Movement**:
- Since the HCl solution is hypotonic, water will move from the dilute solution into the mango to balance the solute concentrations. This influx of water will cause the mango to swell.

5. **Conclusion**:
- Based on the principles of osmosis, we can conclude that when a mango is placed in a dilute aqueous solution of hydrochloric acid, it indeed swells. Therefore, the statement is **True**.

### Final Answer:
**True**
