03) Give reason for the following statements:
a)During summer season, a milk man usually adds a very small amount of baking soda to fresh milk
b) For dilution of acid, water is not added to acid but acid is added into water​

Answer 1

1st reason

Dilution of concentrated acid is an exothermic process. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. When the acid is added to water slowly with constant stirring, the mixture will not splash out.

Answer 2

a. to avoid bursting of milk

b. because water is a universal slvent
