K+ cation muaj tus nqi zoo me me (+1) thiab lub vojvoog loj (vim nws nyob rau hauv plaub kab ntawm lub sijhawm), yog li nws K_a< 1 x 10^-14 Nws yuav tsis hydrolyze dej los yog cuam tshuam rau pH Tus NO3− anion yog tus conjugate puag conjugate puag Rau aqueous tov ntawm ib tug qaug zog acid, qhov dissociation tas li hu ua cov kua qaub ionization tas li (Ka). Ib yam li ntawd, qhov sib npaug tas li rau cov tshuaj tiv thaiv ntawm lub hauv paus tsis muaj zog nrog dej yog lub hauv paus ionization tas li (Kb). Rau tej conjugate acid–base khub, KaKb=Kw. https://chem.libretexts.org › 07:_Acid_and_Base_Equilibria

ntawm cov kua qaub uas muaj zog, yog li nws tsis muaj qhov tseem ceeb (K_b < 1 x 10^{- 14).}

YPuas K puas muaj hydrolysis?

K2SO4 tsis dhau hydrolysis.

YYuav ua li cas dej hydrolyze?

Ib hom hydrolysis tshwm sim thaum cov ntsev ntawm cov kua qaub tsis muaj zog lossis lub hauv paus tsis muaj zog (lossis ob qho tib si) yog yaj hauv dej. Cov dej spontaneously ionizes rau hauv hydroxide anions thiab hydronium cations. Cov ntsev kuj dissociates rau hauv nws cov anions thiab cations.

Yuav ua li cas ions tuaj yeem hydrolyze dej?

Ob hom ions hydrolyze hauv cov tshuaj aqueous: (1) cov ntsev ntawm cov kua qaub tsis muaj zog thiab cov hauv pausthiab (2) qee cov hlau ions.

Yuav ua li cas yog ib qho anion hauv qab no tsis hydrolyze?

NO3-
