'''Calcium hydroxide''', tradeetionally cried '''slaked lime''', is an [[inorganic compoond]] wi the chemical formula [[Calcium|Ca]]([[Hydroxide|OH]])<sub>2</sub>. It is a colourless crystal or white pouder an is obtained when [[calcium oxide]] (cried ''lime'' or ''quicklime'') is mixed, or "[[wiktionary:slake|slaked]]" wi [[watter]]. It haes mony names includin '''hydratit lime''', '''biggers' lime''', '''slack lime''', '''Choona''' (wird used in [[Indie]], [[Pakistan]] an [[Afghanistan]]), '''cal''', or '''picklin lime'''. Calcium hydroxide is uised in mony applications, includin fuid preparation. '''[[Limewatter]]''' is the common name for a ''[[saturatit solution]]'' o calcium hydroxide.
