Question

what is the use of ph in water analysis

Answer 1

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. Alkalinity is ameasure of a river's "buffering capacity," or its ability to neutralize acids.
