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

Fresh milk has higher pH which makes it less acidic and the value of pH of milk decreases, when it turns into curd as the bacteria present in air causes the milk to form curd. Curd is acidic in nature because an acidic substance has less value of pH so it is more acidic.
