If you put milk in coffee how will it affect the pH?

Adding milk to coffee will increase the pH, making it less acidic. Here's why:

* Coffee is acidic: Coffee naturally has a pH of around 4.5 to 5.0, which is considered acidic.

* Milk is slightly alkaline: Milk has a pH of around 6.5 to 6.7, making it slightly alkaline.

* Mixing them: When you add milk to coffee, the alkaline milk will neutralize some of the acidity in the coffee, resulting in a higher pH.

Important Note: The exact pH change will depend on the type of milk used, the amount of milk added, and the strength of the coffee.
