11. Fresh milk has a pH of 6. How do you think the pH will change as it turns into curd? Explain your answer.

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:

The pH value of fresh milk is 6. When it turns into curd, it becomes sour due to formation of lactic acid and hence its pH decreases below 6.
