Raws li Lavoisier thawj txoj kev xav, tag nrho cov acids muaj cov pa oxygen, uas yog lub npe los ntawm Greek ὀξύς (oxys: acid, ntse) thiab hauv paus -γενής (-genes: creator). Tom qab ntawd nws tau pom tias qee cov kua qaub, tshwj xeeb yog hydrochloric acid, tsis muaj oxygen thiab yog li cov kua qaub tau muab faib ua oxyacids thiab cov hydroacids tshiab.
Cov kua qaub twg tsis muaj oxygen?
Cov ntsiab lus hauv cov teeb no (6)
- hydrofluoric acid. HF.
- hydrochloric acid. HCl.
- hydrobromic acid. HBr.
- Yhydroiodic acid. Hlo.
- Yhydrocyanic acid. HCN.
- Yhydrosulfuric acid. H2S.
Puas tag nrho cov kua qaub muaj oxygen thiab hydrogen?
Nws muaj ob yam tseem ceeb: Txhua cov kua qaub yuav tsum muaj cov proton uas tuaj yeem pub dawb. Qhov no txhais tau tias cov tebchaw uas tsis muaj hydrogen (xws li N 2 O) tsis tuaj yeem ua cov kua qaub. Feem ntau, cov proton txuas nrog lub atom electronegative heev (xws li oxygen lossis halogen).
Vim li cas tsis tag nrho cov kua qaub muaj oxygen?
Thaum yaj hauv dej, cov kua qaub tsim H + ions (tseem hu ua protons, txij li tshem tawm ib qho hluav taws xob los ntawm qhov nruab nrab hydrogen atom tawm tom qab ib qho proton). Cov cai rau Naming Acids uas tsis muaj Oxygen nyob rau hauv lub Anion: Vim tag nrho cov acids muaj tib cation, H +, peb tsis tas yuav muab lub npe cation
Yuav ua li cas cov kua qaub muaj oxygen?
Ib oxoacid (qee zaus hu ua oxyacid) yog cov kua qaub uas muaj oxygen. Yuav kom paub meej ntxiv, oxoacid yog cov kua qaub uas muaj cov pa oxygen.
