MCQ
The final product in solvay process is:
  • A
    $\mathrm{Na}_2 \mathrm{CO}_3 $
    ​
  • ✓
    $\mathrm{Na}_2 \mathrm{CO}_3 \cdot 10 \mathrm{H}_2 \mathrm{O}$
  • C
    $\mathrm{Na}_2 \mathrm{CO}_3 \cdot \mathrm{H}_2 \mathrm{O}$
  • D
    $\mathrm{Na}_2 \mathrm{CO}_3 \cdot 8 \mathrm{H}_2 \mathrm{O}$
✓

Answer

Correct option: B.
$\mathrm{Na}_2 \mathrm{CO}_3 \cdot 10 \mathrm{H}_2 \mathrm{O}$
The final product obtained in Solvay process $($also known as ammonia soda process$)$ is $\mathrm{Na}_2 \mathrm{CO}_3 \cdot 10 \mathrm{H}_2 \mathrm{O}$
$2 \mathrm{NaHCO}_3 \rightarrow \mathrm{Na}_2 \mathrm{CO}_3+\mathrm{H}_2 \mathrm{O}+\mathrm{CO}_2$
