What is pH?
ChemistryAcids and bases
Quick Answer
pH is a scale that measures how acidic or basic a solution is. It is based on the concentration of hydrogen ions.
The Full Story
The pH scale usually runs from 0 to 14, with 7 considered neutral at room temperature. Lower values indicate greater acidity, while higher values indicate greater basicity or alkalinity. The concept was introduced by Danish chemist Søren Peder Lauritz Sørensen in 1909 at the Carlsberg Laboratory. pH matters in soil, oceans, medicine, cooking, and industrial chemistry. Even small changes in pH can strongly affect chemical reactions and living systems.
