Question

Give reason During summer season, a milk man usually adds a very small amount of baking soda to fresh milk.

Answer 1

The pH of milk is 6. As the pH of milk reduces , it starts turning into curd. Hence, to prevent that, the milkman adds a small amount of baking soda, which is a base. By doing this he increases the pH of the milk and prevents it from turning into curd sooner.
