Ib kua qaub yog ib qho compound uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, ib kua qaub yog tej yam khoom uas tsim hydronium ions (H3O+) thaum yaj hauv dej . Thaum hydrochloric kua qaub (HCl) dissolves nyob rau hauv dej , nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions.
Tom qab ntawd, hom tshuaj twg ionizes tag nrho thiab tsim hydronium ions thaum yaj hauv dej?
Piav: Ib kua qaub yog ib yam khoom uas cuam tshuam nrog dej los tsim ntau tshaj hydroxonium ions hauv cov kua dej. Hydroxonium ions yog tsim los ntawm cov tshuaj sib txuas ntawm cov pa oxygen ntawm cov dej molecules thiab cov protons tso tawm los ntawm kua qaub vim nws ionization.
Ib yam li ntawd, dab tsi ua rau hydronium ions hauv dej? Raws li Arrhenius 'lub tswv yim ntawm acids, ib tug acid yog xws li ib tug compound uas thaum yaj nyob rau hauv dej , tso proton(s) los yog H+. Tam sim no raws li Arrhenius acid tso tawm H +, cov proton ua ke nrog H2O molecule los tsim H3O + ion qe ib hydronium ion.
Yog li ntawd, dab tsi ion yog tsim thaum lub acid yaj nyob rau hauv dej?
hydrogen
Yuav ua li cas thaum acid yaj nyob rau hauv dej?
Thaum ib acid yog yaj nyob rau hauv dej Nws tsim hydrogen ions (H +) uas ua ke nrog dej los tsim cov hydronium ion (H3O +). Thaum twg Cov kua qaub Yog Dissolved hauv dej Nws Cov txheej txheem Exothermic heev thiab tuaj yeem ua rau hlawv.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi ions tsim thaum barium nitrate yaj hauv dej?
Thaum Ba(NO3)2 yaj nyob rau hauv H2O (dej) nws yuav dissociate (dissolve) rau hauv Ba 2+ thiab NO3- ions
Puas yog Hydronium yog cov kua qaub lossis lub hauv paus?
Hauv cov tshuaj acidic, hydronium yog qhov ua haujlwm ntau dua, nws cov proton ntau dhau tau yooj yim rau cov tshuaj tiv thaiv nrog hom kab mob. Hydronium ion yog acidic heev: ntawm 25 ° C, nws pKa yog kwv yees li 0
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog lub npe rau cov khoom uas yaj hauv dej tab sis tsis tsim ions lossis ua hluav taws xob tam sim no?
Ib qho electrolyte yog ib yam khoom uas tsim cov kua hluav taws xob thaum yaj hauv cov kuab tshuaj polar, xws li dej. Cov yaj electrolyte cais mus rau hauv cations thiab anions, uas disperse uniformly los ntawm cov kuab tshuaj. Hluav taws xob, xws li kev daws teeb meem yog nruab nrab
