Raw materials for 'Solvay Process' for manufacture of the soda ash are
Discuss
Answer & Solution
Answer: Option A
Solution:
The Solvay Process is a widely used industrial method for the manufacture of soda ash (sodium carbonate, Na₂CO₃).

The main raw materials required for this process are salt (NaCl), limestone (CaCO₃), and coke or gas.

Salt (NaCl): Provides the sodium ions necessary for forming sodium carbonate. It is dissolved in water to form brine, which serves as the main source of sodium.

Limestone (CaCO₃): When heated in a kiln, limestone decomposes to form carbon dioxide (CO₂) and quicklime (CaO). The CO₂ generated is used in the carbonation stage of the process.

Coke or Gas: Acts as a fuel to heat the limestone in the kiln, providing the thermal energy required for its decomposition. Coke (carbon) or producer gas can be used to maintain the necessary temperature and also contributes to CO₂ formation.

Although ammonia is used in the process, it is not considered a raw material because it is continuously recovered and reused within the system.

Therefore, the true consumable raw materials in the Solvay Process are salt, limestone, and coke or gas.

Hence, the correct answer is Option A: Salt, limestone and coke or gas.
