===Meaning===
A [[Metal Hydroxide]] is a [[Base|basic]] [[Metal Compound|metal compound]] made of one or more [[Metal]] [[atom]]s and one or more [[Hydroxide]]s [[Oxygen]] [[atomIon (Chemistry)|Hydroxide ion]]s.
===About Metal OxidesHydroxides===: [[Metal OxideHydroxide]]s have a [[pH]] greater than [[Neutral (Chemistry)|7]]: Some All [[Metal Oxide]]s are [[insoluble]] [[solid]]s.: Some [[Metal OxideHydroxide]]s [[dissolve]] in [[water]] to make [[Metal Hydroxide]]s which are an [[alkali]]s.
