Ph water definition
WebDec 27, 2024 · ANSWER: In short, for most people, plain water is better. But first, it’s important to understand the definition of alkaline water. Scientists use pH to describe how acidic or basic a substance is, with a range from 0 to 14. Pure water has a pH of 7, meaning it’s neutral. Fluids with a pH under 7, such as coffee and soda, are acidic. WebAlkalinity is a measure of the acid-neutralizing capacity of water and is usually determined by titration against sulfuric acid to the endpoint of the acid–base reaction. In groundwaters, the carbonate species predominate and an endpoint of about pH 4.5 marks the consumption of bicarbonate in solution.
