pH paranoia: Understanding alkaline water claims | Water ...

A ,pH, less than 7 is ,acidic, and a ,pH, greater than 7 is ,alkaline,. The ,pH, scale is logarithmic so for every one unit of change in ,pH, there is a tenfold change in ion concentration. This means a solution with a ,pH, of 3 is 10 times more ,acidic, than a solution with a ,pH, of 4 and 100 times more ,acidic, than one with a ,pH, of 5.

pH, is a scale of measurement expressing the acidity or alkalinity of the ,wastewater,. In the ,pH, scale, a value below 7 shows that a ,wastewater, is ,acidic,, a value of 7 is neutral, and values higher than 7 are ,alkaline,. The ,pH, values are logarithmic, meaning a ,pH, of 6 is 10 times more ,acidic, than a ,pH, of 7.
