Ib kua qaub yog ib hom tshuaj uas pub cov protons los yog hydrogen ions thiab/los yog txais electrons. Feem ntau kua qaub muaj cov hydrogen atom sib txuas uas tuaj yeem tso tawm (dissociate) los ua ib qho cation thiab anion hauv dej.

Kuj yuav paub yog, dab tsi yog acid muab piv txwv?

Acids yog cov khoom uas tso tawm Hydrogen ions hauv kev daws. Cov kua qaub yog corrosive rau hlau thaum tso tawm Hydrogen gas, muaj pH ntawm 0 thiab 6.9 thiab qaub rau saj. Muaj ntau ntau yam tshuaj uas yog acids: kua txiv qaub (citric acid), vinegar (acetic acid), plab acid, thiab soda pop (carbonic acid).

Secondly, dab tsi yog lub ntsiab lus ntawm acid thiab puag? Hauv qhov kev xav no, ib kua qaub yog ib yam khoom uas tso tau ib tug proton (xws li nyob rau hauv lub Arrhenius txoj kev xav) thiab a puag yog ib yam khoom uas yuav txais tau ib tug proton. Ib qho yooj yim ntsev, xws li Na+F-, generates OH- ions hauv dej los ntawm kev noj cov protons los ntawm dej nws tus kheej (kom HF): F−(aq) + H2O(l)⇌HF(aq) + OH−

Ib yam li ib tug yuav nug, 3 hom acids yog dab tsi?

Feem ntau kua qaub tuaj yeem muab faib ua peb loj hom . Thawj qhov yog binary kua qaub Qhov thib ob yog oxyacid, thiab qhov kawg yog carboxylic kua qaub . Binary kua qaub tag nrho cov ntawv sau nyob rau hauv "H-A", uas txhais tau hais tias hydrogen daim ntawv cog lus rau ib tug nonmetal atom.

Dab tsi yog acid kid txhais?

kua qaub . npe. Cov me nyuam txhais ntawm kua qaub (Nqe 2 ntawm 2): ib qho tshuaj sib xyaw uas qab qaub thiab tsim cov kua dej uas tig xiav litmus daim ntawv liab.
