Ph water definition
WebMay 6, 2024 · pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14. WebApr 26, 2024 · Function. The pH range is from zero to 14, with zero being the most acidic, 14 being the most basic, and seven being neutral. In healthy humans, normal body pH is between 7.35 and 7.45, with an average of 7.4. 1. This slightly alkaline pH level is ideal for many biological processes, such as the oxygenation of blood.
