PH formula

The formula to calculate pH looks something like this: pH=−log10[Hsolvated].

This is a logarithmic equation with a base 10. On this scale, a substance with a ph of 3 is ten times more acidic than a substance with a pH of 4, and 100 times more acidic than a substance with a pH of 5. Similarly, a substance with a pH of 9 is ten times more alkaline than a substance with a pH of 8, and 1000 times more alkaline than a substance with a pH of 6.
