Feem ntau kua qaub tso ions hauv dej , uas ua ke nrog dej molecule ua tsim tawm hydronium () ion. Qhov no ion ua ke nrog dej tsim hydronium ion. Piv txwv. Yog li, luv luv, An kua qaub tsim hydronium ion thaum nws yog yaj hauv dej.
Yog li ntawd, cov kua qaub ua dab tsi thaum yaj hauv dej?
Acids yog tshuaj uas thaum yaj hauv dej tso tawm hydrogen ions, H +(aq). Bases yog cov tshuaj uas muaj kev cuam tshuam nrog thiab neutralize kua qaub , ua dej . Thaum twg yaj , hauv paus tso tawm hydroxide ions, OH-(aq) rau hauv kev daws teeb meem. Dej yog cov khoom ntawm ib kua qaub thiab puag reacting.
Ib yam li ntawd, yuav ua li cas thaum cov kua qaub muaj zog xws li HBr yaj hauv dej? Qhov no txhais tau tias cov kua qaub tsis yog kiag li yaj nyob rau hauv aqueous tov, tab sis tsuas yog ib feem. Hydrogen bromide, HBr , yog a muaj zog acid , li no nws yog equation ntawm dissociation HBr (aq) -> H+(aq) + Nr-(aq). Hydrogen flouride, HF, ua rau qaug zog kua qaub , yog li qhov sib npaug yog HF(aq) H+(aq) + F-(aq).
Yog li ntawd, cov hauv paus tsim dab tsi thaum yaj hauv dej?
Puag : ib yam uas tsim tawm hydroxide ions (OH-) thaum yaj hauv dej . Bases muaj pH ntau dua 7. A puag yog tej yam uas dissolves nyob rau hauv dej thiab tsim tawm hydroxide ions (OH-).
Thaum yaj hauv dej NaOH yuav ua li cas?
Lo lus nug: Thaum Dissolved hauv dej , NaOH Behaves As Cov kua qaub uas tsim Na + thiab OH- Ions. Lub hauv paus uas tsim Na + Thiab OH- Ions. Cov kua qaub uas tsim NaO- thiab H + Ions. Lub hauv paus uas tsim NaO- Thiab H + Ions.

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
Dab tsi yog tsim thaum ntsev yaj hauv dej?
Thaum cov ntsev ntsev, sodium chloride, yaj hauv dej, nws dissociates rau hauv nws cov cations thiab anions, Na + thiab Cl-. Ionic tebchaw xws li sodium chloride, uas yaj nyob rau hauv dej thiab dissociate rau tsim ions, hu ua electrolytes. Thov Saib cov animation 10.3 ntawm kev daws teeb meem ionic
Puas yog cov kua qaub tsim hydronium ions thaum lawv yaj hauv dej?
Cov kua qaub yog ib qho sib xyaw uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, cov kua qaub yog ib yam khoom uas tsim hydronium ions (H3O +) thaum yaj hauv dej. Thaum hydrochloric acid (HCl) yaj nyob rau hauv dej, nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions
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
