WebbReading the pH scale. The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. Webb30 apr. 2024 · The pH scale runs from 0 to 14, where 7 is neutral. Any substance with a pH value below 7 is considered acidic while any substance with a pH value above 7 is considered basic or alkaline. The pH Scale The pH scale is not a new scientific concept. In fact, it was introduced in 1909 by Soren Peter Lauritz Sorensen. duty to refer broxbourne
