Thawj qhov uas yuav tsum nco ntsoov yog tias, vim cov no yog tsis yog binary kua qaub , koj tsis txhob siv lub prefix " hydro "Thaum lawv lub npe npe ntawm kua qaub los tsuas yog los ntawm qhov xwm ntawm anion. Yog tias npe ntawm cov ion xaus hauv "-ate," hloov nws mus rau "-ic" thaum naming lub kua qaub.
Tib neeg kuj nug, txoj cai rau npe cov kua qaub yog dab tsi?
Cov kua qaub muaj npe raws li lawv cov anion - cov ion txuas nrog hydrogen. Cov npe rau tej ntawd kua qaub suav nrog lub npe "hydro-", thawj lub suab ntawm anion, thiab cov lus "-ic". nyuaj kua qaub cov tebchaw muaj oxygen hauv lawv. Rau ib kua qaub nrog polyatomic ion, cov lus "-ate" los ntawm ion yog hloov nrog "-ic."
Ib yam li ntawd, koj lub npe hc2h3o2 li cas? HC2H3O2 yog cov tshuaj formula rau cov organic compound acetic acid. Kuj hu ua ethanoic acid, acetic acid yog cov kua xim tsis muaj xim uas ua lub luag haujlwm tseem ceeb hauv txhua txoj kev lom neeg. Nws cov qauv tshuaj yog qee zaum sau ua CH3COV or CH3CO2H hais txog nws lub koom haum atomic.
Ntxiv mus, dab tsi yog hom kev hu ua Oxyacid?
Ib oxyacid nrog ob lub pa oxygen tsawg dua li cov (hauv paus) ic acid yog lub npe los ntawm kev sau ntawv hypo-, ces lub hauv paus ntawm lub npe rau lub caij uas tsis yog hydrogen thiab oxygen, ces -ous, thiab ces acid. Yog li, HClO, yog hypochlorous acid.
Puas yog HCl yog cation lossis anion?
HCl , uas muaj cov anion chloride, hu ua hydrochloric acid . HCN, uas muaj cov anion cyanide, hu ua hydrocyanic acid. Cov cai rau naming Oxyacids ( anion muaj cov pa oxygen): Vim tias tag nrho cov acids muaj tib yam cation , H+, peb tsis tas yuav sau npe cation.

Vim li cas los nag yog ib txwm acidic tab sis tsis yog tag nrho cov nag raug cais ua kua qaub?
Ntuj Los: Dej nag 'Li qub' yog me ntsis acidic vim tias muaj cov kua carbonic acid yaj. Cov pa roj ntawm cov leej faj oxides thiab nitrogen oxides tau hloov pauv mus ua sulfuric thiab nitric acids. Cov roj uas tsis yog hlau oxide hnov mob nrog dej los tsim cov kua qaub (ammonia ua lub hauv paus)
Koj yuav txiav txim siab li cas yog tias cov kua qaub muaj zog lossis tsis muaj zog?
Yog hais tias ib qho acid tsis tau teev tseg ntawm no, nws yog ib qho tsis muaj zog acid. Nws tuaj yeem yog 1% ionized lossis 99% ionized, tab sis nws tseem raug cais raws li cov kua qaub tsis muaj zog. Txhua cov kua qaub uas dissociates 100% rau hauv ions yog hu ua ib tug muaj zog acid. Yog hais tias nws tsis dissociate 100%, nws yog ib tug qaug zog acid
Dab tsi yog cov tshuaj tiv thaiv ntawm daim ntawv xiav litmus thaum dipped rau hauv cov kua qaub uas muaj tshuaj?
Daim ntawv liab litmus reacts rau alkaline tshuaj los ntawm tig xiav, thaum xiav litmus ntawv reacts rau acidic tshuaj los ntawm tig liab
Ua li cas koj npaj cov pob zeb qub rau cov kua qaub?
Pob zeb Acid Stains tsuas yog cov stains tiag tiag nrog cov txiaj ntsig mus tas li. Kauj Ruam 1: Tshawb xyuas cov pob zeb qub ua ntej staining. Kauj Ruam 2: Tshem cov pob zeb ua ntej staining. Kauj Ruam 3: Ntsuam Xyuas Cov Pob Zeb Qub. Kauj Ruam 4: Stain Lub Pob Zeb. Kauj Ruam 5: Seal Lub Pob Zeb
Koj yuav ua li cas npaj cov pob zeb tshiab rau cov kua qaub?
Kev npaj cov pob zeb pob zeb rau ACID STAIN Siv cov pob zeb ntxuav thiab degreaser. Feem ntau ntawm cov pob zeb pob zeb tsuas yog xav tau kev tu yam tsawg kawg nkaus uas siv cov organic degreaser diluted ntawm qhov nruab nrab concentration nrog dej. Scrub Nto. Yaug cov tshuaj ntxuav thiab degreaser. Tshem tawm cov dej ntau dhau
