Pure water is used for electrolysis of water to get hydrogen.

Answer

### Step-by-Step Solution:

1. **Understanding Electrolysis of Water**:
Electrolysis is a process that involves passing an electric current through water to decompose it into hydrogen and oxygen gases.

2. **Identifying the Nature of Pure Water**:
Pure water is a weak electrolyte, meaning it does not dissociate significantly into ions (H⁺ and OH⁻). This weak dissociation results in a low concentration of charge carriers.

3. **Conductivity of Pure Water**:
Because pure water has very few ions, it is a poor conductor of electricity. This means that when an electric current is applied, the electrolysis process will be very slow.

4. **Need for Conductivity Improvement**:
To enhance the conductivity of the water and facilitate the electrolysis process, we need to increase the number of ions present in the solution.

5. **Adding Acid to Water**:
By adding an acid (such as sulfuric acid or hydrochloric acid) to the water, we introduce additional H⁺ ions. This increases the number of charge carriers in the solution, allowing for better conductivity.

6. **Conclusion**:
Therefore, the statement "Pure water is used for electrolysis of water to get hydrogen" is **false**. Instead, acidified water is used for the electrolysis process to effectively produce hydrogen gas.

### Final Answer:
The statement is **false**. We do not use pure water; we use acidified water for the electrolysis of water to obtain hydrogen gas.
