Solvay Process

Solvay process is an excellent method for the preparation of $\boxed{\pink{Sodium\:Carbonate}}$ . Sodium carbonate in anhydrous state is $Na_2CO_3$ . It is also known as washing soda.

Reactions Involved

$2NH_3\:+\:H_2O+CO_2\:\rightarrow\:{(NH_4)}_2CO_3\\\\{(NH_4)}_2CO_3\:+\:H_2O+CO_2\:\rightarrow\:2NH_4HCO_3\\\\NH_4HCO_3\:+\:NaCl\:\rightarrow\:NH_4Cl\:+\:NaHCO_3$

$\pink{\rightarrow} NaHCO_3$ has low solubility. Its Crystal separates and are heated to give sodium carbonate.

$2NaHCO_3\:\rightarrow\:Na_2CO_3\:+\:CO_2\:+\:H_2O$

Recovery of Ammonia

$NH_3$ can be recovered. The reaction involved is

$2NH_4Cl\:+\:Ca{(OH)}_2\:\rightarrow\:2NH_3\:+CaCl_2\:+\:H_2O$

$\pink{\rightarrow}$ Solvay process can not be extended to the preparation of potassium carbonate because potassium hydrogen carbonate is too soluble to be precipitated by the addition of KCl to ammonium hydrogen carbonate.
