WebbMany chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it … WebbpH Meters pH and ORP are important parameters of water quality and a wide range of process applications depend upon the ability to measure and control each. Both pH and ORP represent types of ion activity in liquids—pH measures hydrogen ion activity while ORP represents the potential transfer of electrons between chemicals or chemical compounds.

WebbpH is a measure of the hydrogen ion activity in a solution. Pure water that contains an equal balance of positive hydrogen ions (H +) and negative hydroxide ions (OH -) has a neutral pH. Solutions with a higher concentration of hydrogen ions (H +) than pure water are acidic and have a pH less than 7.
