Baris 1: {{about\|\|tempat di Azerbaijan\|Alçalı\|other uses\|}} '''Alkali''' (dari [[bahasa Arab]]: ''al-qaly'' القلي, القالي , “abu dari saltwort”) dalam [[kimia]] adalah suatu [[garam]] [[ion~~\|ionik~~]]ik [[basa]] dari suatu [[unsur kimia]] [[alkali logam]] atau [[alkali tanah]]. Ada yang mendefinisikan suatu alkali sebagai suatu zat [[basa]] yang larut dalam [[air]]. Larutan alkali mempunyai [[pH]] lebih dari 7,0. <!--The [[adjective]] '''alkaline''' is commonly, and '''alkalescent''' less often, used in [[English language\|English]] as a [[synonym]] for basic, especially for [[soluble]] bases. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the [[acid-base reaction theories\|Arrhenius]] definition of a base, and they are still among the most common bases. ==Etymology== Baris 12: * Alkalis are normally [[solubility\|water soluble]], although some like [[barium carbonate]] are only soluble when reacting with an acidic aqueous solution. --> == Beda antara alkali dan basa == Istilah "basa" dan "alkali" sering digunakan bergantian, terutama di luar konteks [[kimia]] dan teknik kimia. <!-- Baris 34: Soils with pH values higher than 7.3 are usually defined as being alkaline. These soils can occur naturally, due to the presence of alkali salts. Although some plants do prefer slightly basic soil (including vegetables like [[cabbage]] and fodder like [[buffalograss]]), most plants prefer a mildly acidic soil (with pHs between 6.0 and 6.8), and [[alkaline soil]]s can cause problems.<ref>{{cite book\|title=[[Chambers's encyclopaedia]]: a dictionary of universal knowledge, Volume 1\|publisher=J.B. Lippincott & Co\|year=1888\|page=148}}</ref> --> == Danau alkali == Dalam ''[[danau alkali]]'' (atau ''danau soda''), penguapan terkonsentrasi pada garam-garam karbonat alamiah, menghasilkan danau alkali yang sering kali juga asin. Contoh danau alkali: * [[Alkali Lake (Oregon)\|Alkali Lake]], [[Lake County, Oregon]] * [[Baldwin Lake (San Bernardino County, California)\|Baldwin Lake]], [[San Bernardino County, California]] * [[Mono lake]], near [[Owens Valley]] in [[California]] * [[Redberry Lake, Saskatchewan]] <!-- Not Blueberry lake, ref see http://www.pnr-rpn.ec.gc.ca/nature/whp/sanctuaries/dc01s12.en.html --> * [[Summer Lake (Oregon)\|Summer Lake]], [[Lake County, Oregon]] * [[Tramping Lake, Saskatchewan]] * [[Lake Magadi]] di [[Kenya]] * [[Lake Turkana]] in [[Kenya]] (danau alkali terbesar di dunia) * There are also alkali lakes in the outback of [[Australia]]. == Lihat pula == * [[Basa]] * [[Alkali logam]] * [[Alkali tanah]] == Referensi == {{Reflist\|30em}} [[~~Category~~Kategori:Kimia]]
