When milk is converted in to curd its pH will * A increase B decrease C No change D 7?

Answer: When it changes to curd its pH will decrease. It is because curd contains lactic acid. Since acids generally have a low pH value, when fresh milk changes to curd its pH will decrease.

Why does a milkman add baking soda to fresh milk to shift the pH of fresh milk from 6 to slightly alkaline?

A milkman adds a small amount of baking soda to fresh milk to prevent acidification of milk. By adding a 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 a longer time as the milk in alkaline condition, does not set curd easily.
