Ph water definition
WebFeb 23, 2024 · water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances. WebThe pH of a substance is a measure of how acidic or basic the substance is. Measured on a scale from 0 to 14, pH is based on the concentration of hydrogen ions in a solution. In pure water, which is neutral (neither acidic nor basic), the concentration of hydrogen ions corresponds to a pH of 7.0. This marks the midpoint of the pH scale.
