Question

What is a solvay process describe its various reactions

Answer 1

The Solvay process or ammonia process is the major industrial process for the production of sodium carbonate.

1)The Solvay process results in soda ash(predominantly sodium carbonate(${Na}_2{CO}_3$ ) from brine (as a source of sodium chloride(NaCl) and from limestone(as a source of calcium carbonate (${CaCO}_3$ ).

The overall process is;

$2NaCl+CaC{O}_3⟶N{a}_{2}C{O}_3+{CaCl}_2$

2) In the second step carbon dioxide(${CO}_2$ ) passes through a concentrated aqueous solution of sodium chloride (table salt,NaCl) and ammonia (${NH}_3$ )

$NaCl+C{O}_2+N{H}_3+H_{2}O⟶Na{HCO}_3+{NH}_{4}Cl$
