Answer 1

When barium chloride combines with

sodium sulphate in the form of their

aqueous solutions, a white precipitate

of barium sulphate is formed which is

insoluble in water. The reaction also creates

sodium chloride, which remains dissolved

in water and so cannot be seen. ... So this

reaction is a chemical change.
