Acid - Simple English Wikipedia, the free encyclopedia

An acid is a substance that can donate a hydrogen ion (H +) (generally speaking, this will be a proton) to another substance.Acids have a pH less than 7.0. A chemical can donate a proton if the hydrogen atom is attached to an electronegative atom like oxygen, nitrogen, or chlorine.Some acids are strong and others are weak.The weak acids hold on to some of their protons, while the strong acids .
