Hydrogen

Hydrogen is the lightest gas, so it is found only in combined state and not in air. Hydrogen gas can be obtained from the action of metals with acids, alkalis and water. This note provide us the information about hydrogen and its preparation. Learn More

Nitrogen

Nitrogen is an inert gas which constitutes about 78% by volume of the atmosphere. Nitrogen gas is prepared in the laboratory by heating the mixture of ammonium chloride and sodium nitrite in the ratio of 1:1. This note provides us the information about nitrogen and its preparation. Learn More

Properties Of Hydrogen

The atomic form of hydrogen produced at the time of chemical reaction is known as nascent hydrogen. Hydrogen is a colorless, tasteless and odorless gas. This note provides us the information about nascent hydrogen and its preparation with properties. Learn More

Oxygen

Oxygen is abundantly occurring element on the earth. It constitutes about 47.6% of the earth’s crust. Oxygen gas can be prepared in the laboratory by hydrogen peroxide and manganese dioxide.
