The pH value is a measure of the acidic or basic character of a liquid. Solutions with a pH of 7 are called neutral, with a value below 7 pH acidic and with a value above 7 pH basic (or alkaline).
The pH value is an important variable, so it can control biological or chemical processes, the availability of nutrients or even the activity of microorganisms. Thus, monitoring and controlling the pH of water, soil or food is important for a variety of applications
