Question

Write the balanced chemical equations for the following reactions:

1) Sodium carbonate on reaction with hydrochloric acid in equal molar concentrations gives sodium chloride and sodium hydrogencarbonate.

2) Sodium hydrogencarbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide.

3)

Answer 1

Answer:

1) Sodium carbonate on reaction with hydrochloric acid in equal molar concentrations gives sodium chloride and sodium hydrogencarbonate.

Answer: Na2CO3 + HCl ⇨ NaCl + NaHCO3

2) Sodium hydrogencarbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide.

Answer: NaHCO3 + HCl ⇨ NaCl + H2O + CO2

Answer 2

1) Na2CO3+HCl -- NaCl+ NaHCO3

2)NaHCO3+HCl--NaCl+H2O+CO2
