Qhov sib txawv tseem ceeb ntawm kev sib npaug molecular thiab ionic equation yog qhov sib npaug molecular qhia cov reactants thiab cov khoom nyob rau hauv molecular daim ntawv, thaum lub ionic equation qhia cov ionic hom koom nyob rau hauv cov tshuaj tiv thaiv.
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. Muaj ntau hom kev sib npaug tshuaj, xws li molecular equations thiab ionic equations. Hauv kab lus no, cia peb tshuaj xyuas qhov sib txawv ntawm qhov sib npaug molecular thiab ionic equation.
Dab tsi yog Molecular Equation?
Ib kab zauv molecular sawv cev rau cov reactants thiab cov khoom nyob rau hauv daim ntawv molecular. Nyob rau hauv sib piv, ib qho kev sib npaug ionic muab tsuas yog hom ionic koom nrog cov tshuaj tiv thaiv. Yog li ntawd, nyob rau hauv kev sib npaug molecular, peb yuav tsum tsis txhob suav tej yam ionic hom, tsuas yog molecules. Piv txwv li, cov tshuaj tiv thaiv ntawm sodium chloride thiab nyiaj nitrate muab ib qho dawb precipitate hu ua silver chloride. Qhov sib npaug molecular rau cov tshuaj tiv thaiv no yog raws li nram no:
NaCl + AgNO3 ⟶ AgCl + NaNO3
Ionic Equation yog dab tsi?
Kev sib npaug ionic yog ib txoj hauv kev sau cov tshuaj sib npaug siv cov hom ionic uas tau koom nrog cov tshuaj tiv thaiv. Muaj ob hom kev sib npaug ionic ua tiav ionic equation thiab net ionic equation. Qhov ua tiav ionic kab zauv 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 uas koom nyob rau hauv ib tug tshuaj tiv thaiv.
Qhov sib npaug ionic yog ib qho tshuaj sib npaug uas qhia cov ions uas koom nrog tsim cov khoom kawg. Tsis tas li ntawd, qhov sib npaug no tuaj yeem tau txais los ntawm kev sib npaug ionic tiav 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 tib cov tshuaj tiv thaiv saum toj no, qhov sib npaug ionic yog raws li hauv qab no:
Na+ + Cl– + Ag+ + NO 3– ⟶ AgCl + Na+ + NO3 -
Qhov txawv ntawm Molecular Equation thiab Ionic Equation yog dab tsi?
Molecular equation thiab ionic equation yog ob hom tshuaj sib npaug peb tuaj yeem siv los sawv cev rau cov tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm kev sib npaug molecular thiab ionic equation yog qhov sib npaug molecular qhia cov reactants thiab cov khoom nyob rau hauv molecular daim ntawv, thaum lub ionic equation tsuas qhia ionic hom. Yog li, qhov sib npaug molecular yog muab rau hauv daim ntawv molecular, qhov sib npaug ionic yog muab rau hauv daim ntawv ionic. Piv txwv li, cia peb saib cov tshuaj tiv thaiv ntawm sodium chloride thiab nyiaj nitrate, uas muab ib qho dawb precipitate hu ua silver chloride. Nws cov kab zauv molecular yog NaCl + AgNO3 ⟶ AgCl + NaNO3 hos cov ionic equation yog Na+ + Cl– + Ag+ + NO3– ⟶ AgCl + Na+ + NO3–
Hauv qab infographic qhia txog qhov sib txawv ntawm molecular equation thiab ionic equation.
Summary – Molecular Equation vs Ionic Equation
Molecular equation thiab ionic equation yog ob hom tshuaj sib npaug uas peb tuaj yeem siv los sawv cev cov tshuaj tiv thaiv. Raws li lawv cov npe qhia, qhov sib npaug molecular yog muab rau hauv daim ntawv molecular, thaum qhov sib npaug ionic tau muab rau hauv daim ntawv ionic. Yog li, qhov sib txawv tseem ceeb ntawm kev sib npaug molecular thiab ionic equation yog qhov sib npaug molecular qhia cov reactants thiab cov khoom nyob rau hauv molecular daim ntawv, thaum lub ionic equation tsuas qhia cov ionic hom nyob rau hauv cov tshuaj tiv thaiv.
