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

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.
