WebbAt pH 7, the substance or solution is at neutral and means that the concentration of H + and OH - ion is the same. If pH < 7, the solution is acidic. There are more H + than OH-in … Webbph-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. billy rhodes tallahassee
