In water and neutral solutions, the concentration of hydrogen ions is equal to the concentration of hydroxide ions. All acidic solutions contain more hydrogen ions than hydroxide ions.

Hydroxide; Definition, Formula, Reactions And Examples: H ydroxide is a negatively charged ion consisting of one oxygen and one hydrogen atom bound together by a covalent bond.
