The pH level of a substance describes how acidic or basic it is. Substances with a higher pH level are more basic, while substances with a lower pH level are more acidic. A substance with a pH of 7 is considered neutral,...

Potential hydrogen, or pH, is the measure of the acidity or alkalinity of an aqueous solution. A solution is acidic if its pH is less than 7. If its pH is greater than 7, the solution is basic or alkaline.


The pH of ethanol (C2H5OH) or pure alcohol is 7.33. This means that ethanol is slightly basic.

The pH of a solution measures the amount of hydrogen ions that are in a solution. The term "pH" literally means "the power of hydrogen." The pH of a substance tells how acidic or basic a substance is.

Fresh milk has a pH value that is typically between 6.5 and 6.7, making it slightly acidic. A pH greater than 6.7 indicates that the udders producing the milk are inflamed by pathogens, and milk with a pH lower than 6.5 ...
