Crystals to Kill Germs in Water

Introduction:
Water is essential for human survival, but it can also be a source of harmful germs. These germs can cause a range of illnesses, from mild stomach upset to serious infections. To ensure that water is safe to drink, it needs to be treated to kill any germs present in it. One way to do this is to use crystals.

Potassium permanganate:
Potassium permanganate is a powerful oxidizing agent that is commonly used to treat water. It works by producing oxygen, which in turn kills any germs present in the water. When added to water, potassium permanganate crystals dissolve to form a pink or purple solution. This solution is then added to the water that needs to be treated.

How to use potassium permanganate crystals:
To use potassium permanganate crystals to treat water, follow these steps:
1. Dissolve a small amount of potassium permanganate crystals in a container of water.
2. Wait until the crystals have completely dissolved and the water turns pink or purple.
3. Add the solution to the water that needs to be treated.
4. Stir the water to ensure that the solution is evenly distributed.
5. Wait for at least 30 minutes before drinking the water.

Conclusion:
Potassium permanganate crystals are an effective way to kill germs present in water. However, it is important to use them carefully and follow the instructions closely to ensure that the water is safe to drink.
