Options
- AN a O H , H C l , C O 2
- BN H 4 C l , H 2 O , N a C l
- CN a C l , N H 3 , C a O H 2
- DN a C l , C a C O 3 , H 2 S O 4
Correct answer
C. N a C l , N H 3 , C a O H 2
Step-by-step solution
Solvay’s process of manufacturing of sodium carbonate: 2 N a C l + C a C O 3 + C O 2 + H 2 O → 2 N a H C O 3 + C a C l 2 2 N a H C O 3 → Δ N a 2 C O 3 + H 2 O + C O 2
