Thaum twg HCl molecules yaj lawv tsis sib haum hauv H+ ions thiab Cl- ions. HCl yog ib tug muaj zog acid vim nws dissociates yuav luag tag. Los ntawm qhov sib txawv, ib qho tsis muaj zog acid xws li acetic acid (CH3COOH) ua tsis yog tsis sib haum zoo in dej - ntau H+ ions nyob twj ywm bound-up nyob rau hauv lub molecule.
Tom qab ntawd, ib tus tuaj yeem nug, puas yog HCl ionize hauv dej?
Hydrogen chloride ( HCl ) ionizes tag nrho rau hauv hydrogen ions thiab chloride ions nyob rau hauv dej . Ib tug tsis muaj zog acidis ib tug acid uas ionizes tsuas yog me ntsis hauv aqueoussolution. Tsis muaj zog acids, zoo li muaj zog acids, ua ionize los ua tus H + ion thiab conjugate puag. Vim HCl Nws muaj zog acid, nws conjugate puag (Cl −) qaug zog heev.
Tsis tas li ntawd, hydrochloric acid dissociate hauv dej li cas? Muaj zog kua qaub los yog bases tau tsis sib haum kiag li thaum muab tso rau hauv ib qho kev daws ntawm dej . HCl ib zog kua qaub nrog tus nqi pH ntawm 0 thiab 2. Los xaus, thaum HCl yaj hauv dej , nws cov khoom tsis sib haum rau hauv H + ions thiab Cl-ions thaum covalent bondis tawg ntawm lawv.
Yog li ntawd, puas cov hauv paus dissociate hauv dej?
Arrhenius tau sib cav tias hauv paus yog nruab nrab compoundst uas yog tsis sib haum los yog ionize hauv dej muab OH- ions thiab zoo ion. NaOH yog Arrhenius puag vim nws dissociates hauv dej muab cov hydrooxide (OH-thiab sodium (Na+) cov.
Puas yog cov kua qaub tsis muaj zog cuam tshuam hauv dej?
A qaug zog acid yog ib qho ua tsis yog tsis sib haum tag nrho hauv kev daws; qhov no txhais tau tias a weakacid ua Tsis pub dawb tag nrho nws cov hydrogen ions (H+) hauv kev daws teeb meem. Feem ntau ntawm kua qaub yog qaug zog . Qhov nruab nrab, tsuas yog kwv yees li 1 feem pua ntawm a qaug zog acid daws dissociates hauv dej hauv 0.1 mol / L tov.

Cov ntsia hlau puas yuav xeb sai dua hauv dej ntsev lossis dej tshiab?
Teb: Qhov corrosion ntawm hlau qhia tias muaj tshuaj hloov pauv hauv cov hlau. Rust (hydrous oxide) yog ib qho piv txwv ntawm qhov kev hloov no uas tshwm sim thaum hlau raug dej los yog huab cua ntub. Koj cov ntsia hlau hlau tiag tiag yuav xeb sai dua thiab hnyav hauv dej ntsev
Puas CuSO4 dissociate hauv dej?
Thaum CuSO4 los yog CuSO4. 5H2O yog yaj hauv H2O (dej) lawv yuav dissociate (solve) rau hauv Cu 2+ thiab SO4 2- ions. Cov (aq) qhia tau hais tias lawv yog aqueous – yaj nyob rau hauv dej
Puas yog ch3ch2oh dissociate hauv dej?
CH3CH2OH, lub npe hu ua ethanol, yog ib qho cawv uas muaj cov saw hlau luv luv thiab cov pab pawg hydrophilic. Cawv muaj peev xwm yaj hauv dej vim yog pawg cawv thaum kawg, tab sis raws li cov saw hlau carbon loj hlob ntev dua los yog loj dua (vim yog branching), solubility txo
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
Puas yog calcium nitrate dissociate hauv dej?
Thaum Ca(NO3)2 yaj nyob rau hauv H2O (dej) nws yuav dissociate (dissolve) rau hauv NH4+ thiab 2NO3- ions. Txhawm rau qhia tias lawv tau yaj hauv dej peb tuaj yeem sau (aq) tom qab txhua. Cov (aq) qhia tau hais tias lawv yog aqueous – yaj nyob rau hauv dej
