Hydrogen peroxide
Hydrogen peroxide Hydrogen peroxide [Oxyenated Water] is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution, it appears colorless. Due to its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Hydrogen peroxide is therefore used as a propellant in...

Water Water contains only hydrogen and oxygen atoms in the ratio 2 : 1 hence its molecular formula is . Pure water is bad conductor of electricity due to very low degree of ionisation. Its density is maximum at 4°C. Density of ice is less than that of water due to hydrogen bonding therefore ice floats on water. It reacts with the elements placed above hydrogen in electrochemical series to give hydrogen gas under different temperatures (according to the activity of the element) water acts both as oxidising and reducing agent,...

Hydrogen It was discovered by Cavendish and named by Lavoiser. Symbol—H Electronic Configuration = Atomic Mass-1.008 Atomic Number-1 Hydrogen is the first element in the periodic table. The nucleus of the hydrogen atom contains one proton and no neutron. The atom has one planetary electron present in the K—shell. Hydrogen resembles with the alkali metals of I-A group (can lose an electron). It also resembles with halogens of VII-A group (can gain an electron). But it has been alloted a separate and distinct place unassociated with any...
