Qhov Tseem Ceeb Qhov Sib Txawv - Sib npaug sib npaug vs Net Ionic Equation
Txhua cov tshuaj tiv thaiv tuaj yeem sau ua qhov sib npaug. Cov khoom ntawm qhov sib npaug no suav nrog cov reactants nrog lawv lub cev lub cev, ib tug xub qhia cov kev taw qhia ntawm cov tshuaj tiv thaiv thiab cov khoom ntawm cov tshuaj tiv thaiv nrog lawv lub cev lub xeev. Yog tias muaj tej yam tshwj xeeb siv, lawv kuj tau sau luv luv rau ntawm xub. Yog hais tias cov tshuaj tiv thaiv nyob rau hauv sib npaug, ob ib nrab xub siv nyob rau hauv opposite lus qhia. Ib qho kev sib npaug tshuaj tuaj yeem sau ua ob txoj hauv kev: raws li kev sib npaug sib npaug lossis ua ib qho kev sib npaug ionic. Qhov sib txawv tseem ceeb ntawm qhov sib npaug sib npaug thiab qhov sib npaug ionic yog qhov sib npaug sib npaug qhia tau hais tias txhua qhov kev cuam tshuam uas tshwm sim hauv ib qho system ua ke thaum net ionic equation tsuas yog qhia cov tshuaj tiv thaiv uas tshwm sim tom qab ua tiav cov tshuaj tiv thaiv tshwj xeeb.
Dab tsi yog qhov sib npaug?
Tshuaj tiv thaiv tseem ceeb heev rau kev nkag siab txog tus cwj pwm ntawm ib lub cev. Los ntawm kev sau cov kab zauv tseeb rau cov tshuaj tiv thaiv, ib tus tuaj yeem tau txais ib lub tswv yim txog kev hloov ntawm ntau hom hauv qhov system. Rau cov tshuaj tiv thaiv yooj yim xws li kev tawg ntawm NaCl hauv dej, qhov sib npaug tuaj yeem sau tau yooj yim los ntawm kev kwv yees cov khoom ua tau ntawm cov tshuaj tiv thaiv ntawd. Tab sis rau lwm cov kev cuam tshuam nyuaj, kev sim ntxiv yuav tsum tau ua txhawm rau txhawm rau txhawm rau paub cov khoom ntawm cov kab ke tshwj xeeb. Tab sis feem ntau ntawm cov sij hawm, qhov sib npaug ntawm cov ntawv sau muaj feem ntau yuav tsis muaj qhov sib npaug, uas ua rau nws nyuaj rau piav qhia txog kev coj tus cwj pwm ntawm lub cev. Yog li ntawd, kev sib npaug tsis sib npaug yuav tsum sib npaug. Qhov sib npaug sib npaug suav nrog tag nrho cov reactants thiab cov khoom ntawm qhov system. Qhov sib npaug yog sau los ntawm kev xav txog cov tshuaj reactant ua ib qho molecule. Piv txwv li, qhov sib npaug sib npaug ntawm KI thiab PbNO3 (yog tias cov no tshwm sim hauv dej) yuav yog;
Qhov tseem ceeb ntawm qhov sib npaug sib npaug yog tias nws nthuav tawm cov nqi ntawm cov tshuaj reactants uas yuav tsum tau ntxiv muab cov ntsiab lus hais txog kev sib raug zoo ntawm stoichiometric ntawm cov tsiaj hauv lub cev. Hauv qhov piv txwv saum toj no, qhov piv ntawm PbNO3 thiab KI yuav tsum yog 1: 2 thaum ntxiv cov khoom sib xyaw rau hauv lub cev.
Dab tsi yog Net Ionic Equation?
Qhov sib npaug ionic qhia tsuas yog tag nrho cov tshuaj tiv thaiv uas tau tshwm sim hauv lub cev. Nws suav nrog hom ionic thiab cov khoom tsim. Tab sis nws tsis qhia tag nrho cov kev tshwm sim uas tau tshwm sim hauv ib qho system. Piv txwv li, yog tias muaj cov tshuaj tiv thaiv ntawm ob lub molecules siv dej ua qhov nruab nrab, cov tebchaw yuav tau yaj hauv dej thiab sib cais ua ions. Qee yam ntawm cov ions no tuaj yeem koom nrog hauv cov tshuaj tiv thaiv tab sis qee qhov yuav tsis ua. Tom qab ntawd qhov sib npaug ionic net suav nrog tsuas yog cov ions uas koom nrog cov tshuaj tiv thaiv net. Lwm cov ions, uas yog hu ua spectator ions, raug tshem tawm ntawm qhov sib npaug kom tau qhov sib npaug ionic. Piv txwv li, yog KI thiab PbNO3 tshwm sim hauv dej, cov tshuaj tiv thaiv ionic yuav yog;
Qhov no kuj tseem suav nrog K+ ion thiab NO3– ion, tab sis cov ions tsuas yog yaj thiab tsis koom nrog. cov tshuaj tiv thaiv loj; Yog li, lawv tsis suav nrog cov tshuaj tiv thaiv ionic.
Dab tsi yog qhov sib txawv ntawm Qhov Sib npaug thiab Net Ionic Equation?

Summary – Balanced Equation vs Net Ionic Equation
Thaum qee cov ionic ntxiv rau hauv dej, lawv tawg thiab tsim ions uas yaj hauv dej. Qhov no tsim anions thiab cations. Txhawm rau qhia txog cov khoom tsim tawm tom qab ua tiav cov tshuaj tiv thaiv thiab cov kev taw qhia ntawm cov tshuaj tiv thaiv, cov tshuaj sib npaug tuaj yeem sau tau. Qhov kev sib npaug no tuaj yeem sib npaug los txiav txim siab tus naj npawb ntawm cov atoms ntawm txhua hom uas nyob ntawm ob sab ntawm xub; Qee zaum, txawm tias tus nqi ntawm cov hom no yuav tsum tau txiav txim siab. Qhov no muab ib qho kev sib npaug tshuaj sib npaug rau cov kab ke tshwj xeeb. Txawm li cas los xij, net ionic equation suav nrog tsuas yog hom reacted. Raws li tau hais ua ntej lawm, qhov sib txawv tseem ceeb ntawm qhov sib npaug sib npaug thiab qhov sib npaug ionic yog qhov sib npaug sib npaug qhia tau hais tias txhua qhov kev cuam tshuam hauv qhov system whereas net ionic equation qhia tsuas yog cov tshuaj tiv thaiv uas tshwm sim thaum ua tiav cov tshuaj tiv thaiv tshwj xeeb.
