Question

A milkman added a small amount of baking soda to fresh milk :
1 what do you expect to observe when milk comes to boil

Answer 1

(a) By adding small amount of baking soda, the milkman shifts the pH of the fresh milk from 6 to slightly alkaline so that he can keep it for longer time as the milk in alkaline condition, does not set curd easily.

(b) Due to the addition of baking soda this milk becomes slightly basic because of which acids produced in this milk due to bacterial actions are neutralized. Hence, this milk takes longer time to set as curd.

Answer 2

Answer:

Becoz baking soda is a base which reacts with acids and neutralizes it. This prevents milk from getting sour and keeping it fresh for long time.

Hope it help you ✌️❣️
