WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. WebSep 9, 2024 · The pH scale is a familiar concept for students who study science. The pH value of a solution reflects the relative concentration of hydrogen ions (H+) or protons to the concentration of hydroxide ions (OH-) in a solution. Solutions with a pH value less than 7 are acidic and those with a value greater than 7 are basic, or alkaline.

WebFeb 1, 2024 · Acid + Basic = Salt + Water. PH: It is a measure of how acidic or basic a compound is and the PH range generally is 0 to 14.
