Answer

Solution

Sodium carbonate (Soda Ash) is manufactured by following process. 1. Leblanc process. 2. Solvay‘s ammonia soda process. 3. Dual process (modified Solvay‘s process) 4. Electrolytic process. In Solvay process Common Salt (NaCl) and limestone (CaCO₃) are used as a raw material.

Saponification is simply the process of making soapsOHCOH/(.Soapsarejustpotassiumorsodiumsaltsoflong-) chain fatty acids. During saponification, ester reacts with an inorganic base to produce alcohol and soap. it occurs when triglycerides are reacted with potassium or sodium hydroxide (lye) to produce glycerol and fatty acid salt, called ‘soap’.
