(b)Why does this milk take along time to set into curd?​

Answer 1

Answer:

hello

Explanation:

Curd is acidic in nature, because an acidic substance has less value of pH. A milkman adds a very small amount of baking soda to fresh milk. Why does he shift the pH of the fresh milk from 6 to slightly alkaline? Answer: By making the milk more alkaline, it takes more time to turn into 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 ✌️❣️
