What chemicals purify water?
The most common disinfection method involves some form of chlorine or its compounds such as chloramine or chlorine dioxide. Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use.
Is Iodine used to purify water?
Iodine used for water purification is commonly added to water as a solution, in crystallized form, or in tablets containing tetraglycine hydroperiodide that release 8 mg of iodine per tablet. The iodine kills many, but not all, of the most common pathogens present in natural fresh water sources.
Which of these chemicals is not used to purify water?

What are the three ways to purify water?
Three Ways To Purify Water
- Boiling: Bring the water to a rolling boil for 3-5 minutes. Let cool before drinking.
- Disinfect: You can use household liquid bleach (regular household bleach contains 5.25% sodium hypochlorite) to kill microorganisms.
- Distillation: Fill a pot halfway with water.
What chemicals are in water?
Examples of chemical contaminants include nitrogen, bleach, salts, pesticides, metals, toxins produced by bacteria, and human or animal drugs. Biological contaminants are organisms in water. They are also referred to as microbes or microbiological contaminants.

How do you make pure water?
Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water.
Which gas is used in purification of drinking water?
Disinfection usually involves a form of chlorine, especially chloramines or chlorine dioxide. Chlorine is a toxic gas, resulting in some danger from release associated with its use.
Do they put chlorine in drinking water?
The U.S. Environmental Protection Agency (EPA) allows drinking water treatment plants to use chloramine and chlorine to disinfect drinking water. Chlorine is also used up quickly in water systems. Sometimes there is not enough chlorine left to kill germs in the water by the time it reaches the end of the pipes.

How can I purify my water without a filter?
If you don’t, then you can try rock boiling.
- Create a vessel to hold your water (such as out of pine bark)
- Make a fire.
- Heat rocks in the fire.
- Put hot rocks in the vessel with the water.

What are the types of purification?
The general methods of purification are:
- Sublimation.
- Crystallisation.
- Distillation.
- Differential Extraction.
- Chromatography.
