Question

fresh milk has a ph of 6. How do you think the ph will change as it turns into curd? Explain your answer​

Answer 1

Answer:

The pH value of milk is 6 since it is acidic in nature. When the milk is converted into curd due to the action of bacteria, lactic acid is formed which is more acidic in nature. Therefore the pH value of the milk is reduced as it turns to curd
