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.

Yuav kua txiv qaub kua txiv puas ua rau cov nroj tsuag?
Siv Lemon Juice Properly pouring txiv qaub kua txiv, txawm diluted, mus rau nplooj tuaj yeem ua rau lawv shrivel, cuam tshuam cov nroj tsuag muaj peev xwm ua photosynthesis. Qhov no yooj yim yog tias koj tab tom sim tshem cov nroj, tab sis tsis nrog cov nroj tsuag koj xav kom ciaj sia .
Puas yog kev puas tsuaj tag nrho cov hnub qub muaj cov neeg ua si hauv zos?
Qhov tseeb tu siab yog tias Kev puas tsuaj AllStars tsis muaj ib hom kev sib tw hauv zos, thiab qhov no feem ntau raug suav tias yog ib qho loj tshaj uas tuav nws. Txawm hais tias nws tsis yog qhov txaus ntshai hauv qhov tob li kev tsav tsheb simulator lossis kev sib ntaus sib tua tsheb, nws tseem muaj kev lom zem ua si rau lub sijhawm luv luv .
Dab tsi ua rau cov kua qaub ua kua qaub?
Ib tug kua qaub yog ib yam khoom uas pub hydrogen ions Vim li no, thaum cov kua qaub yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hydroxide ions Hydroxide yog diatomic anion nrog tshuaj formula OH - Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo.
