Question

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 saponication reaction

Answer 1

Essential chemicals are oil, sodium hydroxide solution. To determine the nature of reaction mixture of saponification reaction we can dip a litmus paper, red litmus will turn blue indication the alkaline nature of reaction mixture.

Answer 2

Chemicals required: Vegetable oil, common salt and 20% sodium hydroxide
solution
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.
