The purity of NaCI solid is checked by measuring boiling point of its saturated solution `(TorF)`

Explanation

To determine whether the statement "The purity of NaCl solid is checked by measuring the boiling point of its saturated solution" is true or false, we can analyze the relationship between boiling point and purity.

### Step-by-Step Solution:

1. **Understanding Boiling Point Elevation**:
- The boiling point of a solution is affected by the presence of solutes (impurities). This phenomenon is known as boiling point elevation.
- When a non-volatile solute (like NaCl) is dissolved in a solvent (like water), the boiling point of the solution increases compared to the pure solvent.

2. **Effect of Impurities**:
- If NaCl is pure, the boiling point of its saturated solution will be at a specific temperature.
- If there are impurities present in the NaCl, the boiling point of the saturated solution will change (typically increase).

3. **Measuring the Boiling Point**:
- By measuring the boiling point of the saturated solution of NaCl, one can determine if the NaCl is pure or not.
- If the measured boiling point is higher than the expected boiling point for pure NaCl, it indicates the presence of impurities.

4. **Conclusion**:
- Therefore, the statement that the purity of NaCl solid is checked by measuring the boiling point of its saturated solution is indeed true.

### Final Answer:
The statement is **True**.
