Question

What is the pH level of pure milk?

Answer 1

Milk is a mixture, so pure milk varies with its content. So pH varies too.

Answer 2

The pH of milk at 25° C normally varies within a relatively narrow range of 6.5 to 6.7 due to the many components in milk, which provide a buffering action. The major buffering groups of milk are caseins and phosphate.
