===Meaning===
A [[Metal Hydroxide]] is a [[Base|basic]] [[Metal Compound|metal compound]] made of one or more [[Metal]] [[atom]]s and one or more [[HydroxideIon (Chemistry)|Hydroxide ion]]s that have the [[Chemical Formula|formula]] OH.
===About Metal OxidesHydroxides===
: [[Metal Hydroxide]]s have a [[pH]] greater than [[Neutral (Chemistry)|7]]
: All [[Metal Hydroxide]]s [[dissolve]] in [[water]] to make an [[alkali]].
