Zoo ib yam li molecular kev sib npaug , uas qhia cov tebchaw li molecules, ib kev sib npaug ionic yog tshuaj kev sib npaug nyob rau hauv uas cov electrolytes nyob rau hauv aqueous tov yog qhia raws li dissociated ions.
Ntawm no, koj sau cov tshuaj tiv thaiv ionic li cas?
Txhawm rau sau tag nrho ionic equation:
- Pib nrog kev sib npaug molecular.
- Soluble muaj zog electrolytes (sib xyaw nrog (aq) ntawm lawv) rau hauv lawv cov ions. qhia cov mis kom raug thiab tus nqi ntawm txhua ion. qhia tus lej tseeb ntawm txhua ion.
- Nqa tag nrho cov sib xyaw nrog (s), (l), lossis (g) tsis hloov.
Ib yam li ntawd, dab tsi ua rau ib qho ionic compound? Ionic compounds yog tshuaj sib xyaw ua los ntawm ions . Cov no ions yog atoms uas nce lossis poob electrons, muab lawv tus nqi zoo lossis tsis zoo. Cov hlau zoo li plam electrons, yog li lawv dhau los ua cations thiab muaj cov txiaj ntsig zoo. Nonmetals zoo li tau txais electrons, tsim cov anions uas muaj tus nqi tsis zoo.
Ib sab saum toj, dab tsi yog qhov sib npaug ionic muab piv txwv?
Ib kev sib npaug ionic yog tshuaj kev sib npaug qhov twg cov electrolytes nyob rau hauv aqueous tov yog sau li dissociated ions . Piv txwv 1) Sodium chloride(aq) + silver nitrate(aq) → silver chloride(s) + sodium nitrate(aq) >>Ag+(aq) + Cl-(aq) → AgCl(s) 2) Sodium(s) + hydrochloric acid (aq) -> sodium chloride (aq) + hydrogen (g)
Dab tsi yog ionic thiab net ionic equations?
Cov ntsiab lus. Cov net ionic equation qhia tsuas yog hom tshuaj uas koom nrog hauv cov tshuaj tiv thaiv, thaum lub ua kom tiav ionic equation kuj suav nrog cov neeg saib ions . Peb tuaj yeem nrhiav tau net ionic equation siv cov kauj ruam hauv qab no: Sau qhov sib npaug molecular kev sib npaug , suav nrog lub xeev ntawm txhua yam khoom.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Net ionic cov tshuaj tiv thaiv yog dab tsi?
Net ionic equation yog ib qho tshuaj sib npaug rau cov tshuaj tiv thaiv uas teev tsuas yog cov tsiaj uas koom nrog cov tshuaj tiv thaiv. Net ionic kab zauv feem ntau yog siv nyob rau hauv acid-base neutralization tshwm sim, ob chav displacementreactions, thiab redox tshua
Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?
Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
