Question

what is pH scale? The pH value of fresh milk is 6 what would be the change in pH after it's conversion into curd?​

Answer 1

Answer:

In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. At room temperature, pure water is neither acidic nor basic and has a pH of 7.

The pH scale is used to measure the acidity of a substance. The pH of milk is 6 while that of curd is of the range 4.5 - 5.5. The pH decreases as milk changes into curd. This is because of the formation of lactic acid which as the name suggests is acidic in nature.
