Hint:
The Solvay process produces soda ash from brine.
The correct answer is: Sodium chloride
- The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate.
- The Solvay process produces soda ash from brine and limestone.
2NaCl + CaCO3 
Na2CO3 + CaCl2
- In the Solvay process, the starting material which can be easily obtained from seawater is sodium chloride.
