The preparation of purified water involves the removal of impurities, contaminants, and minerals from regular water to achieve a high level of purity. Here’s a common method used for preparing purified water:

Distillation Method:

1. Boiling: Regular tap water or any water source is heated in a distillation apparatus. As the water heats up, it begins to evaporate, leaving behind impurities, contaminants, and minerals in the original container.

2. Condensation: The water vapor rises from the boiling container and moves into a separate cooling chamber. This cooling chamber contains a condenser coil or other cooling mechanism. As the water vapor cools down, it condenses back into liquid form.

3. Collection: The condensed purified water is collected in a separate container. This water is now purified because most impurities and contaminants have been left behind in the original container during the boiling process.

4. Mineral Removal: While distillation removes many impurities, it also removes minerals from the water. This can result in demineralized water that might taste flat. Some methods add minerals back to the purified water to enhance its taste and balance.

It’s important to note that distillation is just one method of purifying water. Other methods include reverse osmosis, deionization, and various filtration processes. Each method has its own strengths and limitations, and the choice of method depends on the specific purity requirements and the intended use of the purified water, whether for laboratory use, pharmaceutical production, or other applications.
