Rahul adds aqueous solution of barium chloride to an aqueous solution of sodium sulphate. What would he observe?

Class 10th Xam idea - Science Model Test Paper

Answer :

When an aqueous solution of barium chloride reacts to an aqueous solution of sodium sulphate then precipitate of barium sulphate is formed along with sodium chloride because barium (Ba) is more reactive than Sodium (Na) so it will displaced to sodium from sodium sulphate. It is double displacement reaction.

BaCl₂ + Na₂SO₄ BaSO₄ + 2NaCl

In one of the industrial processes used for manufacture of sodium hydroxide, a gas X is formed as by-product. The gas X reacts with lime water to give a compound Y which is used as a bleaching agent in chemical industry. Identify X and Y giving the chemical equation of the reactions involved.

Xam idea - Science

When a mixture of gases X and Y is compressed to 300 atm. pressure and then passed over a catalyst consisting of a mixture of zinc oxide and chromium oxide (heated to a temperature of 300 �C), then an organic compound Z having the molecular formula CH40 is formed. X is a highly poisonous gas which is formed in appreciable amounts when a fuel burns in a limited supply of air; Y is a gas which can be made by the action of a dilute acid on an active metal; and Z is a liquid organic compound which can react with sodium metal to produce hydrogen gas.

(a) What are X, Y and Z?

(b) Write a balanced chemical equation of the reaction which takes place when X and Y combine to form Z. Indicate the conditions under which the reaction occurs.
