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 saponification reaction. ???​

Answer 1

Answer:

your answer is here !

Explanation:

Raw Materials Required For preparation of soap in laboratory are :

*Vegetable oil

*Sodium Hydroxide

*Commom salt

Test to determine the nature of reaction mixture: 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.

follow me !

Answer 2

Soap is prepared by heating animal fat or vegetable oil with concentrated sodium .

Heat

Fat or oil + NaOH ----------> Soap +Glycerol.

The process of making soap by the hydrolysis of fats and oils with alkalis is called Saponification.

Raw Materials Required For preparation of soap in Laboratory :

--> Vegetable oil

---> Sodium Hydroxide

---> Commom salt

---> Beaker

---> Bunsen Burner.

TEST: saops are mostly basic in nature and we can do litmus test red litmus will turn to blue..

Hope it helps uh... ❤
