Question

mention the essential material chemical to prepare scap in the laboratory. describe in brief the test determining the nature (acidic)(alkaline)of the reaction mixture of sponification reaction?

GIVE Me ANSWER URGENTLY.

Answer 1

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

Answer 2

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.
