Qhov Tseem Ceeb Qhov txawv - Ua tiav Ionic vs Net Ionic Equation
Cov tshuaj tiv thaiv tshuaj yog kev sib cuam tshuam ntawm cov tshuaj sib xyaw ua ke los tsim cov tebchaw tshiab lossis hloov kho lawv cov qauv tshuaj. Cov tebchaw uas dhau los ntawm qee cov tshuaj tiv thaiv yog hu ua reactant, thiab qhov peb tau txais thaum kawg hu ua cov khoom. Kev sib npaug tshuaj lom neeg yog ib qho piv txwv ntawm cov tshuaj tiv thaiv tshuaj siv cov cim tshuaj. Qhov sib npaug tshuaj qhia tau hais tias cov reactants yog dab tsi thiab cov khoom yog dab tsi. Ua tiav ionic equation thiab net ionic equation yog ob txoj hauv kev los sawv cev cov tshuaj tiv thaiv tshuaj. Qhov sib txawv tseem ceeb ntawm Kev Ua tiav ionic thiab net ionic equation yog qhov ua tiav ionic kab zauv muab tag nrho cov hom ionic koom nrog cov tshuaj tiv thaiv thaum net ionic cov tshuaj tiv thaiv muab cov tshuaj lom neeg koom nrog hauv kev tsim cov khoom kawg.
Yam ua tiav Ionic yog dab tsi?
Kev ua tiav ionic yog ib qho kev sib npaug tshuaj uas piav qhia cov tshuaj tiv thaiv, qhia meej txog hom ionic tam sim no hauv kev daws. Ib hom ionic yog ib qho anion (tsis zoo them hom) lossis cation (zoo them hom). Nyob rau hauv sib piv, ib tug ua tiav molecular sib npaug muab cov molecules koom nyob rau hauv ib tug tshuaj tiv thaiv. Cia peb xav txog ib qho piv txwv kom nkag siab txog lub tswv yim no.
Cov tshuaj tiv thaiv ntawm NaCl (sodium chloride) thiab AgNO 3 (silver nitrate) tsim cov xim dawb. Qhov sib npaug molecular rau cov tshuaj tiv thaiv yog raws li hauv qab no.
NaCl + AgNO3 → AgCl + NaNO3
Daim duab 01: Tsim AgCl Precipitate
Cov tshuaj tiv thaiv no tshwm sim hauv qhov nruab nrab aqueous. NaCl dissociates rau hauv cations thiab anions nyob rau hauv aqueous tov raws li hauv qab no.
NaCl → Na+ + Cl–
Tom qab ntawd cov ions no tau txais cov tshuaj tiv thaiv nrog nyiaj nitrate ua AgCl dawb precipitate. Raws li qhov sib npaug saum toj no, tom qab cov tshuaj tiv thaiv, NaNO3 yog tsim los ntawm cov khoom lag luam. Txawm li cas los xij, qhov tshwm sim tiag tiag yog, Na+ thiab NO3– ions raug tso tawm rau hauv nruab nrab aqueous, thiab lawv nyob hauv lawv daim ntawv ionic. Tom qab ntawd qhov ua tiav ionic sib npaug rau cov tshuaj tiv thaiv tshuaj no tuaj yeem sau ua,
Na+ + Cl– + Ag+ + NO 3– → AgCl + Na+ + NO3 -
Qhov kab zauv no muab cov ntsiab lus tag nrho txog cov tshuaj tiv thaiv sib xyaw thiab cov khoom kawg. Kev ua tiav ionic ntawm cov tshuaj tiv thaiv tuaj yeem siv tau kom tau txais qhov sib npaug ionic.
Net Ionic Equation yog dab tsi?
Qhov sib npaug ionic yog ib qho kev sib npaug tshuaj uas qhia tias cov ions tau koom nrog kev tsim cov khoom kawg. Qhov kev sib npaug no tuaj yeem tau txais los ntawm kev ua tiav ionic equation los ntawm kev tshem tawm cov ions zoo sib xws los ntawm ob sab ntawm kev ua tiav ionic. Yog li ntawd, net ionic kab zauv tsis muab cov ntsiab lus hais txog tag nrho cov hom ionic tam sim no nyob rau hauv cov tshuaj tiv thaiv sib tov. Rau cov tshuaj tiv thaiv ntawm NaCl thiab AgNO3, net ionic equation tuaj yeem tau raws li hauv qab no.
Kev ua tiav ionic:
Na+ + Cl– + Ag+ + NO 3– → AgCl + Na+ + NO3 -
Qhov sib npaug ionic:
Na+ + Cl– + Ag+ + NO 3– → AgCl + Na+ + NO3 -
Cl– + Ag+ → AgCl –
Qhov sib npaug ionic saum toj no qhia tias Chloride ions thiab nyiaj cations yog lub luag haujlwm rau kev tsim ntawm AgCl dawb precipitate thiab qhov no tsis suav nrog cov ions seem (Na+ thiab NO 3–). Cov ions tshem tawm yog hu ua "spectator ions" uas tsis koom nrog hauv kev tsim cov nag lossis daus.
Dab tsi yog qhov txawv ntawm Ua tiav Ionic thiab Net Ionic Equation?

Summary – Ua tiav Ionic vs Net Ionic Equation
Kev ua tiav ionic thiab net ionic equation yog ob hom tshuaj sib npaug uas siv los piav txog hom tshuaj uas muaj nyob rau hauv cov tshuaj tiv thaiv sib xyaw lossis hom tshuaj lom neeg uas koom nrog qee yam tshuaj tiv thaiv. Qhov sib txawv ntawm Kev Ua tiav ionic thiab net ionic equation yog qhov ua tiav ionic kab zauv muab tag nrho cov hom ionic koom nrog cov tshuaj tiv thaiv thaum net ionic cov tshuaj tiv thaiv muab cov tshuaj lom neeg koom nrog hauv kev tsim cov khoom kawg.
