Question

What is the pH of Milk?

Answer 1

Part 1: pH

• The pH of any solution is defined as the negative log of Hydrogen ion concentration.
• Mathematically, $\mathrm{pH}=-{\log }_{10}\left[{\mathrm{H}}^{+}\right]$
• pH is used to determine the nature of the solution whether it is acidic, basic, or neutral.

Solution	pH range
Acidic	1 - 6.9
Neutral	7
Basic	7.1 - 14

Part 2: Identifying the pH of Milk

• Depending on the values of pH we can further classify the solution as strongly and weakly acidic and basic.
• The pH level of milk lies between 6.5 to 6.7 and it is slightly acidic in nature.
• However, the pH level can vary as there are different sources of milk. We get milk from mammalian species and even from certain plants. Non-dairy milk like cashew, soy, coconut, and almond milk have pH levels of around 6.
• In the case of coconut milk, when it is taken out fresh it is slightly alkaline, and when it starts drying it becomes acidic.
