    Solution

    Milk is slightly acidic or close to neutral pH. The exact value of a sample depends on when the milk was produced by the cow, The pH of a glass of cow milk ranges from 6.4 to 6.8. Milk fresh from the cow typically has a pH between 6.5 and 6.7. The pH of milk changes over time. As milk goes sour, it becomes more acidic and the pH gets lower.
