Question

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

Answer 1

Explanation:

The pH of fresh milk is 6 which is acidic in nature. This milk is converted to curd by the action of bacteria which further increases the acidity of the curd and decreases its pH value from 6 and it becomes less than 6. The acidic strength increases on going down the pH scale from 7 to 1.

Answer 2

I think that the pH would decrease as curd have Lactic acid present in it. The pH of acidic nature is 0-6 and fresh milk has already 6 pH.so, curd 's pH will decrease.

hope this helps you
