Question

Write a balanced chemical equation with state symbols for the
following reactions.
Solutions of barium chloride and sodium sulphate in water react
to give insoluble barium sulphate and the solution of sodium
chloride
(1) Sodium hydroxide solution in water reacts with hydrochlorid
acid solation in water to produce sodium chloride solution and
water
​

Answer 1

Answer:

(i) BaCl2 + Na2SO4 → BaSO4 + 2NaCl

When an aqueous sodium sulphate solution reacts with an aqueous barium chloride solution, insoluble barium sulphate and sodium chloride solution are formed.

hope it's helpful

Answer 2

Answer:

BaCl2 +Na2So4 ----> 2NaCl+BaSo4

NaOH+HCl --------> NaCl +H2o
