Question

Explain:Formation of barium
sulphate precipitate​

Answer 1

Answer:

For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. ... The reactants changes into ions when dissolved in water and there is an exchange of ions in solution. This results in the formation of product molecule.

When you dissolve them in water, barium sulfate precipitates out and sodium chloride remains in solution. This is called a double decomposition reaction. ... In solution, neither of these compounds can really be said to exist - it is a sea of Na+ and Ba+ ions, and Cl- and SO4- ions, constantly changing partners.
