Mango dipped in concentrated NaCl solution will

Options

A. Burst
B. Contract
C. Swell
D. No effect

Answer

### Step-by-Step Solution:

1. **Understanding the Scenario**: The question asks what happens to a mango when it is dipped in a concentrated NaCl (salt) solution.

2. **Concentration Comparison**: In this scenario, the concentration of solutes (salt) inside the mango is lower than the concentration of solutes in the NaCl solution. This means the mango has a higher concentration of water compared to the surrounding solution.

3. **Osmosis Process**: Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, water will move from the mango (lower solute concentration) to the NaCl solution (higher solute concentration).

4. **Effect on the Mango**: As water leaves the mango to balance the solute concentrations, the mango will lose water. This loss of water will cause the cells in the mango to shrink, leading to a decrease in the overall size of the mango.

5. **Conclusion**: Therefore, when a mango is dipped in a concentrated NaCl solution, it will contract or shrink due to the loss of water.

6. **Final Answer**: The correct answer is that the mango will **contract**.
