Question

Write the balanced chemical equations for the
following reactions.
(a) Sodium carbonate on reaction with hydrochloric
acid in equal molar concentrations gives sodium
chloride and sodium hydrogencarbonate.
(b) Sodium hydrogencarbonate on reaction with
hydrochloric acid gives sodium chloride, water
and liberates carbon dioxide.
(c) Copper sulphate on treatment with potassium
iodide precipitates cuprous iodide (Cuzl2/Cul),
liberates iodine gas and also forms potassium
sulphate.​
