Question

Write and explain the double displacement reaction between sodium sulphate and
Barium chloride . Why is called as precipitation reaction?​

Answer 1

Answer:

1. Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature..
2. A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name.

Answer 2

Answer:

ok

Explanation:

sodium sulphate reacts with barium chloride to give sodium chloride and barium sulphate it is called precipitation reaction as it forms a compound which

is insoluble in water
