6/3/2012, · Changes in acidity can be caused by atmospheric deposition (acid rain), surrounding rock, and certain ,wastewater, discharges. The pH scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ,ions,, which ,make, up water (H+ + OH- = H2O). When both types of ,ions, are in equal concentration, the pH is 7.0 or neutral.

Analysis Method for pH and Alkalinity | Water Resources ...

When the pH is above 7.0, the water is alkaline, or basic (there are more hydroxide ,ions, than hydrogen ,ions,). Since the scale is logarithmic, a drop in the pH by 1.0 unit is a 10-fold increase in acidity. So, a water sample with a pH of 5.0 is ten times as ,acidic, as one with a pH of 6.0. pH 4.0 is 100 times as ,acidic, as pH 6.0.
