3 Soaps are made up of: a limestone and soda c. sodium and potassium salts b. sodium carbonate and silica d. calcium sulphate and salts​

Answer 1

Answer:

The Correct Answer is Option (c): sodium and potassium salts

Explanation:

Sodium fatty acid salt (soap) and glycerin are produced when a hot caustic alkali solution, such as caustic soda (sodium hydroxide), reacts with natural fats or oils, such as tallow or vegetable oil (or glycerol). All soapmaking is based on this saponification reaction.

Soaps are fatty acid salts that are soluble in water and contain sodium or potassium. Oils and fats, or fatty acids, are used to make them. They're made by heating fats and oils and reacting them with a liquid alkali.
