pH is a measure of how ,acidic, or basic (alka­ line) a solution is. It measures the hydrogen ion (H+) activity in a solution, and is expressed as a negative logarithm. The pH measurements are given on a scale of 0.0 to 14.0 (Figure 11-1). Pure water has a pH of 7.0 and is ,neutral,; water measuring under 7.0 is ,acidic,…
