About the ph scale

by Berthold
(Texas)

One thing worthy of remembering about the pH scale. The pH scale is logarithmic. That means each change of one in pH value is 10 times more or less acidic.

Examples:

A solution with a pH of 6.0 is ten times more acidic than pure water (pH 7.0)

A solution with a pH of 9.0 is one hundred times more basic than pure water.
