Cov tsis muaj ionic equation yog chemical equation fora tshuaj tiv thaiv uas teev tsuas yog cov hom koom nrog hauv tshuaj tiv thaiv . Cov tsis muaj ionic Kev sib npaug feem ntau yog siv rau hauv acid-base neutralization cov tshuaj tiv thaiv , ob chav txav cov tshuaj tiv thaiv , thiab redox cov tshuaj tiv thaiv.
Ntawm no, ua li cas koj sau ib qho kev sib npaug ionic?
Sau tag nrho ionic equation:
- Pib nrog kev sib npaug molecular.
- Soluble muaj zog electrolytes (sib xyaw nrog (aq) ib sab ntawm lawv) rau hauv lawv cov ions. qhia cov mis kom raug thiab nqi ntawm txhua ion. qhia tus lej tseeb ntawm txhua ion.
- Nqa tag nrho cov sib xyaw nrog (s), (l), lossis (g) tsis hloov.
Tom qab ntawd, lo lus nug yog, puas muaj qhov sib npaug ionic yog tias tsis muaj nag lossis daus? A net ionic equation yuav tsum sib npaug ntawm ob sab tsis yog nyob rau hauv cov nqe lus ntawm atoms ntawm lub ntsiab, tab sis kuj nyob rau hauv cov nqe lus ntawm hluav taws xob nqi. Yog tag nrho cov khoom yog aqueous, a tsis muaj ionicequation sau tsis tau vim tag nrho ions raug tshem tawm raws li cov neeg saib ions . Yog li ntawd, tsis muaj nag lossis daus tshuaj tiv thaiv tshwm sim.
Yog li ntawd, dab tsi yog qhov sib npaug molecular thiab net ionic?
A molecular equation Nws muaj txiaj ntsig vim nws qhia meej tias cov tshuaj twg tau siv hauv cov tshuaj tiv thaiv. A kev ua tiav tiav qhia tag nrho cov ions hauv kev daws teeb meem, thaum a net ionic equation qhia tsuas yog cov ions uas koom nrog cov tshuaj tiv thaiv rau cov khoom tsim.
Dab tsi yog qhov txawv ntawm ib qho ionic equation thiab ib qho kev ua tiav ionic?
Koj ua kom tiav ionic equation suav tag nrho ionsin kev daws teeb meem, suav nrog cov neeg saib ions . Koj tsis muaj ionicequation tawm ntawm spectator ions thiab tsom ntsoov rau qhov kev hloov pauv hauv tshuaj tiv thaiv. Kuv tawm ntawm sodium thiab chloride ions vim lawv tsis sib haum hauv cov tshuaj tiv thaiv andre hu ua spectator ions.

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
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 ionic yog dab tsi?
Zoo ib yam li cov kab zauv molecular, uas qhia cov tebchaw raws li cov molecules, ib qho kev sib npaug ionic yog ib qho kev sib npaug tshuaj uas cov electrolytes hauv cov tshuaj aqueous tau nthuav tawm raws li cov ions dissociated
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
