Question

While studying saponification reaction for the preparation of soap, a teacher suggested to a student to add a small quantity of common salt to the reaction mixture. The function of common salt in this reaction is to (A) reduce the alkalinity of the soap (B) reduce the acidity of the soap (C) enhance the cleansing capacity of soap (D) favour precipitation of soap

Answer 1

option d because common salt helps in precipitation of soap because common salt reduces the solubility of a soap.

Answer 2

option d is correct because the common salt added thus prevents the preparation of soap by decreasing its solubility
