Webph-wert is a measure of how acidic/basic water is. The range goes off 0 to 14, with 7 being neutral. pHs of less than 7 enter acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a really important measurement concerned water quality. WebA pH of 7 (pure water) is neutral; a pH higher than 7 is basic (alkaline); and less than 7 is acidic. pH is measured on a logarithmic scale. This means that each 1.0 change in pH (positive or negative) is a difference of a factor of 10. Thus a pH of 8.0 is 10 times more basic than 7.0 and 100 times more basic than 6.0. The average pH for sea ...
