To … WebThe alkalinity of water is a measurement of its buffering capacity, which is its ability to neutralize acid or to resist acidification. In contrast, pH is a logarithmic scale for expressing Hydrogen (H +) ion concentration. A solution of pH 7.0 is considered to be neutral, whereas a solution above pH 4.5 is considered to have alkalinity. share accommodation sydney nswWebWhen 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. pool filter timer switch
