Question

A milkman adds a very small amount of baking soda to fresh milk
(a). Why does he shift the PH of the milk from 6 to slightly alkaline?
(b). Why does this milk take a long time to set curd ?​

Answer 1

Answer:

By adding a very small amount of baking soda to fresh milk, the milkman keeps the milk unspoiled for little more time than usual time. As the pH value increases the milk turns to slightly alkaline, ... Hence this milk takes a long time to set as a curd.

________Yes ! The Milkman add small amount of baking soda in fresh milk to make the pH increase from 6 to slightly alkaline . Milkman do it because after increasing pH milkman make the milk more basic if the pH decreases the milk will be spoiled and become undrinkable . By doing so milkman maintain the pH of milk and that way milk will preserve for longer use
