Question

One of the by-products formed during the recovery of $N{H}_3$ from solvay process is

• A. $CaC{l}_2$
• B. $Ca{\left(OH\right)}_2$
• C. $NaHC{O}_3$
• D. $N{H}_{4}Cl$

Answer 1

The correct option is A

$CaC{l}_2$

Solvay (ammonia soda) process is used for the manufacture of washing soda $\left(N{a}_{2}C{O}_3\right)$.

Recovery of $N{H}_3$:$2N{H}_{4}Cl+Ca{\left(OH\right)}_2\to 2N{H}_3+CaC{l}_2+H_{2}O$
By product : $CaC{l}_2$
