Starting with sodium chloride how would you proceed to prepare sodium carbonate? Mention the steps only.

Text Solution

Verified by Experts

Sodium carbonate may be obtained by passing `CO_2` through ammoniacal brine (Solvay ammonia soda process) when `NaHCO_3` gets precipitated. This on heating gives `Na_2CO_3`.
`NaCl + NH_3 + CO_2 + H_2O to NaHCO_3 darr + NH_4Cl`
`2NaHCO_3 to Na_2CO_3 + CO_2 + H_2O`
