Full Answer

The pH scale indicates the acidity or alkalinity of a substance. A pH of 7 is neutral. Anything below that is acidic. As the pH number becomes smaller, the acidity increases. Vinegar's pH level is 3, so it is 30 times more acidic than milk with a pH level of 6. A pH level above 7 indicates an alkalide or base. The higher the number, the more alkaline the liquid.
