MCQs On Hydrogen Peroxide

Hydrogen peroxide is one of the most versatile chemical compounds that can be put to use in numerous ways. Its composition is essentially just hydrogen and oxygen. Just like ozone that consists of just oxygen, hydrogen peroxide has several properties. Hydrogen peroxide (H2O2) is an important oxidant, used in various fields of industry, such as paper manufacturing, production of polymers, detergents, and cosmetics. There are few organic and naturally available cures for several of our health issues and one of them is hydrogen peroxide. With antioxidant and anti germs properties, hydrogen peroxide is prescribed by many doctors around the world as preventive measures and cures for diseases involving pathogens.
