Question

On addition of barium chloride solution to sulphuric acid: 

a) a gas is evolved

b) Colour of the solution changes

c) Precipitate is formed

d) No reaction takes place​

Answer 1

Answer:

option A

Explanation:

Evolution of gas

Answer 2

Answer:

c) Precipitate is formed

Explanation:

1. The reaction of barium chloride with dilute sulphuric acid forms a white precipitate of barium sulfate and hydrochloric acid.

2. Sulfuric acid is commonly met as an aqueous solution in the laboratory.

3. When barium chloride and sulfuric acid solutions are mixed, barium ions and sulfate ions exist in the same solution for a moment.

4. Immediately, with the mixing you will see a white precipitate is formed.

5. That white precipitate is barium sulfate.
