Question

preparation of soap and cement.
​

Answer 1

Answer:

The French chemist Eugene-Michel Chevreul put the soap-forming process (called in English saponification) into concrete chemical terms in 1823. In saponification, the animal fat, which is chemically neutral, splits into fatty acids, which react with alkali carbonates to form soap, leaving glycerin as a byproduct.

Answer 2

Soap can be made from the base hydrolysis of a fat or an oil. This hydrolysis is called saponification, and the reaction has been known for centuries. Traditionally, soaps were made from animal fat and lye (NaOH). (Lye was traditionally made by pouring water through wood ashes.)

Cement is manufactured by heating a precise mixture of finely ground limestone, clay and sand in a rotating kiln to temperatures reaching 1450ºC. This results in the production of cement clinker, an intermediate product in the manufacture of cement.
