Verified by Experts

Sodium carbonate : Brine is saturated with ammonia. Then `CO_(2)` is passed into the solution. Sodium bicarbonate is formed due to the following reactions.
`NH_(3) + H_(2)O + CO_(2) to NH_(4)HCO_(3)`
`NaCl + NH_(4)HCO_(3) to NaHCO_(3) + NH_(4)Cl`
The sodium bicarbonate on clacination gives sodium carbonate.
`2NaHCO_(3) to Na_(2)CO_(3) + H_(2)O + CO_(2)`.
