Hauv acidic kev daws teeb meem, hydronium yog qhov ua haujlwm ntau dua, nws cov proton ntau dhau tau yooj yim rau cov tshuaj tiv thaiv nrog yooj yim hom. Cov hydronium ion yog heev acidic : ntawm 25 ° C, nws pKib yog kb0.

Ntawm no, yog h3o ib qho kua qaub los yog lub hauv paus?

Cov H3O+ yog conjugate kua qaub ntawm H2O. Yog li H3O+ yog siv raws li ib tug shorthand rau ib tug proton nyob rau hauv aqueous tov. Hauv cov tshuaj uas tsis yog-aqueous, proton yuav tsim cov qauv sib txawv. Qhia tau tias H2O yog tsim los ntawm qhov sib npaug H + thiab OH- ions thiab yog amphoteric (yuav ua tau ib qho acid los yog puag ) muaj daim ntawv deprotonated (OH-).

Qhov thib ob, yog Hydronium yog Lewis acid? Txawm tias cov hydronium ion yog lub npe Lewis acid Ntawm no, nws tsis yog nws tus kheej lees txais ib khub electron, tab sis tsuas yog ua raws li lub hauv paus ntawm proton uas ua haujlwm nrog cov Lewis puag.

Hauv qhov no, h3o+ puas muaj zog lossis qaug zog acid?

Tag nrho cov carboxylic kua qaub yog tsis muaj zog acids . Cov muaj zog acids yog HCl, HBr, HI, HNO3, HClO4, thiab thawj hydrogen ntawm H2SO4. Hauv muaj zog acids , cov [ H3O+ ] yog ze rau qhov sib npaug ntawm qhov concentration ntawm cov kua qaub . Hauv tsis muaj zog acids , cov [ H3O+ ] yog deb tsawg tshaj qhov concentration ntawm cov kua qaub.

pH ntawm h3o + yog dab tsi?

Qhov concentration ntawm hydronium ion tuaj yeem pom los ntawm cov pH los ntawm qhov thim rov qab ntawm kev ua lej ua haujlwm ua haujlwm kom pom cov pH . [ H3O+ ] = 10- pH los yog [ H3O+ ] = antilog (- pH ) Piv txwv: Dab tsi yog qhov hydronium ion concentration hauv cov tshuaj uas muaj a pH ua 8,34!
