While studying the saponification reaction, what do you observe when you mix an equal amount of colorless vegetable oil and 20% aqueous solution of NaOH in a beaker?(A) The color of the mixture has become dark brown.(B) A brisk effervescence is taking place in the beaker.(C) The outer surface of the beaker has become hot.(D) The outer surface of the beaker has become cold.
Correct Answer: (C) The outer surface of the beaker has become hot.
Explanation: A whitish suspension was formed by heating the mixture of vegetable oil and 20% NaOH solution and that the beaker’s surface was warm when touched as it is an exothermic reaction.
