Question

Write the balanced chemical equations for the following reactions:

1. Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide gas.
2. Copper sulphate on treatment with potassium iodide precipitates cuprous iodide (CuI) liberates iodine gas and also forms potassium sulphate.

Answer 1

​​​​​​The balanced chemical equations for the given chemical reactions are:

1. ${\mathrm{NaHCO}}_3+\mathrm{HCl}\to \mathrm{NaCl}+H_{2}O+{\mathrm{CO}}_2$
2. $2{\mathrm{CuSO}}_4+4\mathrm{KI}\to 2\mathrm{CuI}+I_2+2K_2{\mathrm{SO}}_4$
