Water suitable for accurate laboratory work can be obtained by _____

Explanation

**Step-by-Step Solution:**

1. **Understanding the Requirement**: The question asks how to obtain water suitable for accurate laboratory work. This implies that the water must be pure and free from impurities that could affect experimental results.

2. **Identifying the Purity of Water**: For laboratory work, it is essential to use pure water. Impurities in water can interfere with chemical reactions and lead to inaccurate results.

3. **Choosing the Right Process**: The best method to obtain pure water is through the process of distillation. Distillation is a technique used to separate components of a mixture based on differences in their boiling points.

4. **Explaining Distillation**: In distillation, water is heated to convert it into vapor. The vapor is then cooled and condensed back into liquid form. This process effectively removes impurities because they do not evaporate with the water.

5. **Collecting the Pure Water**: The condensed vapor is collected, resulting in pure water. Since the impurities remain in the original container, the water obtained through distillation is suitable for laboratory use.

6. **Conclusion**: Therefore, the answer to the question is that water suitable for accurate laboratory work can be obtained by **distillation**.
