Question

Write the balanced chemical equations for the following reactions
(i) Solutions of barium chloride and sodium sulphate in water
reacts to give barium sulphate and sodium chloride.
(ii) Sodium hydroxide solution reacts with hydrochloric acid to
produce sodium chloride and water.​

Answer 1

Answer:

BaCl2(aq) + Na2So4(aq) gives BaSo4(s) + 2NaCl

Explanation:

When a solution of barium chloride and sodium sulphate in water reacts to give insoluble barium sulphate and the solution of sodium chloride then this represents a double displacement reaction.

As in a double displacement reaction there is exchange of two ions between the two compounds.

The chemical reaction equation for the reaction will be as follows.

BaCl2(aq) + Na2So4(aq) gives BaSo4(s) + 2NaCl
