Question

What happens when an aqueous solution of sodium sulphate reacts with an aqueous solution of barium chloride? State the physical conditions of reactants in which the reaction between them will not take place. Write the balanced chemical equation for the reaction and name the type of reaction.

Answer 1

When sodium sulphate reacts with barium chloride it forms a white precipitate (barium sulphate).

Balanced equation with physical states are:
Na²So4 (aq) + BaCl² (aq) —> BaSO4 (s) + 2Nacl (aq)

Its a Double Displacement Reaction.

Answer 2

Double displacement reaction takes place and white coloured precipitates in the form of barium sulphate is produced
