Mention the essential material (chemicals) to prepare soap in the laboratory. Describe in brief the test of determining the nature (acidic/alkaline) of the reaction mixture of saponification reaction.
Chemicals required to prepare soap in the laboratory are: Vegetable oil, common salt, and 20% sodium hydroxide solution.
Test of determining the nature (acidic/alkaline) of the reaction: When a red litmus paper is dipped in the reaction mixture, the paper changes its colour to blue. Hence, the reaction mixture of the saponification reaction is basic in nature.
