Mutta mist\u00e4 happamuus oikeastaan johtuu? T\u00e4t\u00e4 kysymyst\u00e4 pohti ranskalainen kemisti <b>Antoine Lavoisier<\/b>.<\/p>\n<p>Lavoisier tunnetaan erityisesti palamisen mekanismin selvitt\u00e4misest\u00e4, ja h\u00e4nt\u00e4 pidet\u00e4\u00e4n yhten\u00e4 modernin kemian perustajista. Tutkiessaan rikkihappoa ja monia muita happamia aineita h\u00e4n huomasi, ett\u00e4 niiss\u00e4 kaikissa esiintyi happea. T\u00e4m\u00e4n perusteella h\u00e4n p\u00e4\u00e4tteli, ett\u00e4 juuri happi synnytt\u00e4\u00e4 happojen ominaisuudet.<\/p>\n<p>T\u00e4st\u00e4 ajatuksesta syntyi my\u00f6s alkuaineen nimi. Englannin sana &#8220;oxygen&#8221; pohjautuu kreikan sanoihin, jotka tarkoittavat &#8220;happoa synnytt\u00e4v\u00e4\u00e4&#8221;. Nimi heijastaa siis suoraan Lavoisier&#8217;n k\u00e4sityst\u00e4.<\/p>\n<h3>Todellinen happamuuden aiheuttaja olikin vety<\/h3>\n<p>My\u00f6hemm\u00e4t tutkimukset kuitenkin paljastivat, ettei asia ollutkaan niin yksinkertainen. Rikkihapon happamuus ei johdu hapesta, vaan sen sis\u00e4lt\u00e4mist\u00e4 <b>vetyioneista<\/b>.<\/p>\n<p>Nykyk\u00e4sityksen mukaan aine on hapan silloin, kun se pystyy luovuttamaan vetyioneja (H+). Toisin sanoen Lavoisier ep\u00e4ili v\u00e4\u00e4r\u00e4\u00e4 &#8220;syyllist\u00e4&#8221;. H\u00e4n osoitti sormellaan happea, vaikka todellinen syyllinen olikin vety. Tilanne muistuttaa salapoliisiromaania, jossa ensimm\u00e4inen ep\u00e4ilty osoittautuu t\u00e4ysin syytt\u00f6m\u00e4ksi ja oikea tekij\u00e4 l\u00f6ytyy vasta lopussa.<\/p>\n<p>T\u00e4m\u00e4 ei kuitenkaan v\u00e4henn\u00e4 Lavoisier&#8217;n merkityst\u00e4 tieteen historiassa.

Rajallisista tiedoista ja vaatimattomista tutkimusv\u00e4lineist\u00e4 huolimatta h\u00e4n pyrki selitt\u00e4m\u00e4\u00e4n luonnon ilmi\u00f6it\u00e4 j\u00e4rjestelm\u00e4llisesti. Juuri t\u00e4llainen ajattelutapa vei kemiaa valtavin harppauksin eteenp\u00e4in.<\/p>\n<h3>Vaikka nimi j\u00e4i v\u00e4\u00e4r\u00e4ksi, sen tausta tekee siit\u00e4 helposti muistettavan<\/h3>\n<p>Tieteess\u00e4 on yll\u00e4tt\u00e4v\u00e4n paljon nimi\u00e4, jotka heijastavat vanhoja k\u00e4sityksi\u00e4 eiv\u00e4tk\u00e4 nykyist\u00e4 tietoa.
