Question

Complete the following equation by writing products and calculate the molecular mass of the reactants and products. 1) Copper sulphate + Sodium carbonate. 2)Barium cloride+sodium sulphate 3) Lead nitrate+sodium cloride​

Answer 1

Explanation:

a) Sodium carbonate is the common chemical which has the common name washing soda and this compound is white crystalline in nature. - Copper sulphate crystals when added to water form aqueous solution which is blue in colour. ... Thus, the precipitate formed will be the copper carbonate.

b)Reaction between barium chloride and sodium sulphate is an example of double displacement reaction. - On mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed, which is an insoluble product and as we can see that the reaction is irreversible.

c) Sodium chloride solution when added to lead nitrate solution, results in the formation of a precipitate of lead chloride and sodium nitrate.
