Qhov txawv ntawm magnesium chloride thiab magnesium sulfate yog magnesium chloride molecule muaj ib magnesium cation txuam nrog ob chloride anions whereas magnesium sulfate molecule muaj ib magnesium cation txuam nrog ib sulfate anion.
Magnesium yog ib qho alkaline ntiaj teb hlau uas tuaj yeem tsim cov cation ruaj khov divalent. Cov cation no tuaj yeem tsim ntau cov ionic xws li magnesium chloride thiab magnesium sulfate. Ob qho no yog cov khoom sib txuas ntawm chav tsev kub uas tuaj yeem muaj nyob hauv ntau hom hydrated. Kab lus no tham txog cov ntsiab lus ntxiv txog ob lub tebchaw no thiab lwm qhov sib txawv ntawm lawv.
Magnesium Chloride yog dab tsi?
Magnesium chloride yog ib qho inorganic compound uas muaj cov tshuaj formula MgCl2 Nws tuaj yeem muaj nyob hauv ntau hom hydrate. Cov tebchaw no yog ionic halides thiab yog cov dej soluble heev. Peb tuaj yeem tau txais cov ntaub ntawv hydrated los ntawm seawater los ntawm kev sib txawv extractions. Cov molar loj ntawm daim ntawv anhydrous yog 95.211 g / mol. Nws yog xim dawb mus rau xim tsis muaj xim crystalline.
Daim duab 01: Magnesium Chloride Crystals
Lub ntsiab lus melting ntawm qhov no yog 714◦C, thiab qhov kub ntawm qhov kub yog 1412◦C. Lub crystallization ntawm cov compound no zoo li cadmium chloride crystallization. Nws muaj octahedral Mg chaw. Cov dej ntau tshaj plaws suav nrog magnesium chloride txuam nrog 2, 4, 6, 8 thiab 12 dej molecules.
Magnesium Chloride muaj ib Magnesium Cation txuam nrog ob Chloride Anions
Peb tuaj yeem tsim cov tshuaj no los ntawm Dow txheej txheem uas magnesium hydroxide kho nrog HCl acid kom tau magnesium chloride thiab dej.
Mg(OH)2 + HCl → MgCl2 + H2O
Cov ntawv thov ntawm cov khoom siv no suav nrog kev tsim cov hlau magnesium los ntawm electrolysis, plua plav tswj, av stabilization, raws li kev txhawb nqa rau Ziegler-Natta catalyst, thiab lwm yam.
Magnesium Sulfate yog dab tsi?
Magnesium sulfate yog ib qho inorganic compound uas muaj cov tshuaj formula MgSO 4 Nws yog ntsev ntawm magnesium thiab tuaj yeem muaj nyob hauv ntau hom hydrated ib yam nkaus. Cov molar loj ntawm daim ntawv anhydrous yog 120.36 g / mol. Nws zoo nkaus li dawb crystalline khoom ntawm chav tsev kub. Cov tshuaj no tsis muaj ntxhiab tsw. Nws tsis muaj melting point. Hloov chaw, nws decomposes ntawm 1124◦C.
Daim duab 02: Anhydrous Magnesium Sulfate
Tsis zoo li magnesium sulfate, qhov sib xyaw no tsis yog dej ntau heev. Cov ntaub ntawv hydrated muaj xws li magnesium sulfate txuam nrog 1, 4, 5, 6 thiab 7 dej molecules.
Magnesium Sulfate Molecule muaj ib Magnesium Cation txuam nrog ib qho Sulfate Anion
Cov kev siv ntawm cov tshuaj no yog nyob rau hauv cov tshuaj raws li cov ntxhia rau cov tshuaj zus tau tej cov magnesium, muab tshuaj txhuam ntawm no compound yog pab tau nyob rau hauv kev kho mob ntawm daim tawv nqaij mob, thiab lwm yam, nws yog ib qho tseem ceeb nyob rau hauv kev ua liaj ua teb los mus nce lub qib magnesium thiab sulfur hauv av.
Qhov txawv ntawm Magnesium Chloride thiab Magnesium Sulfate yog dab tsi?
Xav txog cov qauv molecular ntawm ob qho tib si, magnesium chloride molecule muaj ib qho magnesium cation txuam nrog ob chloride anions whereas magnesium sulfate molecule muaj ib magnesium cation txuam nrog ib sulfate anion. Qhov no yog qhov sib txawv tseem ceeb ntawm magnesium chloride thiab magnesium sulfate.
Tsis tas li ntawd, magnesium chloride yog ib qho inorganic compound uas muaj cov tshuaj formula MgCl
2 Cov molar loj ntawm daim ntawv anhydrous yog 95.211 g / mol. Tsis tas li ntawd, cov hydrates feem ntau suav nrog magnesium chloride txuam nrog 2, 4, 6, 8 thiab 12 dej molecules. Magnesium sulfate yog ib qho inorganic compound uas muaj cov tshuaj formula MgSO4 Cov molar loj ntawm daim ntawv anhydrous yog 120.36 g / mol. Ntxiv mus, cov ntaub ntawv hydrated muaj xws li magnesium sulfate txuam nrog 1, 4, 5, 6 thiab 7 dej molecules.
Summary – Magnesium Chloride vs Magnesium Sulfate
Magnesium yog ib pawg 2 tshuaj lom neeg uas tuaj yeem tsim cov cations ruaj khov, sib txawv uas muaj peev xwm tsim cov ionic compounds. Magnesium chloride yog ib qho ionic halide, thiab magnesium sulfate yog magnesium ntsev. Qhov sib txawv ntawm magnesium chloride thiab magnesium sulfate yog magnesium chloride molecule muaj ib magnesium cation txuam nrog ob chloride anions whereas magnesium sulfate molecule muaj ib magnesium cation txuam nrog ib sulfate anion.
