In laboratory, calcium sulphate is prepared by the action of sulphuric acid on calcium chloride, calcium oxide or calcium carbonate. ..

Calcium carbonate is prepared in the laboratory by passing carbon dioxide gas into lime water. The resulting precipitate is filtered, washed and dried. The product obtained is known as precipitated chalk. Excess of carbon dioxide should be avoided since this leads to the fo..

Methane is prepared in the laboratory by the action of sodium acetate on soda lime. (Soda lime = NaOH + CaO..

By treating sodium sulphite or bisulphite with dilute sulphuric acid or hydrochloric acid - The apparatus is set up as shown in figure 7.1. Sodium sulphite or bisulphite is taken in a round bottom flask. Dilute sulphuric or hydrochloric acid is added through the dropping funnel and heated gently. S..

Some common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H 2 SO 4 ) and Nitric acid (HNO 3 ). Some of the lesser used acids are Acetic acid (CH 3 COOH), Hydrofluoric acid (HF), Carbonic acid (H 2 CO 3 ). Hydrofluoric acid is a high..

Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it constitutes about 88% by ..
