Qhov sib txawv tseem ceeb ntawm magnesia thiab magnesium yog tias magnesia yog inorganic compound magnesium hydroxide, whereas magnesium yog ib qho tshuaj lom neeg.
Magnesia yog tshuaj lom neeg uas tau los ntawm magnesium. Ob leeg yog inorganic Chemistry nyob rau hauv inorganic chemistry.
Magnesia yog dab tsi?
Magnesia lossis mis nyuj ntawm magnesia yog magnesium hydroxide. Nws yog cov tshuaj sib xyaw uas muaj cov tshuaj formula Mg (OH) 2. Cov tshuaj no yog cov khoom dawb, tab sis tsis zoo li magnesium oxide, qhov sib xyaw no tsis yog hygroscopic vim tias nws muaj dej solubility tsawg. Magnesia tshwm sim nyob rau hauv qhov zoo li cov ntxhia brucite.
Peb tuaj yeem tsim cov tshuaj no yooj yim los ntawm kev ntxiv dej rau magnesium oxide. Los yog lwm yam, peb tuaj yeem tsim nws los ntawm kev sib xyaw cov tshuaj magnesium ntsev nrog dej alkaline. Yog li, qhov tshuaj tiv thaiv no ua rau muaj nag lossis daus ntawm magnesium hydroxide. Txawm li cas los xij, hauv kev lag luam nplai, peb tsim cov khoom siv no los ntawm kev kho dej hiav txwv nrog txiv qaub. Ntxiv mus, qhov tshuaj tiv thaiv no muab tons ntawm magnesium hydroxide.
Thaum xav txog kev siv cov khoom sib xyaw no, nws yog qhov tseem ceeb tshaj plaws raws li lub hauv paus rau kev tsim cov magnesium oxide. Nyob rau hauv nws daim ntawv ncua kev kawm ntawv, cov khoom no yog ib qho tseem ceeb raws li ib tug antacid los yog ib tug laxative. Ntxiv mus, nws muaj txiaj ntsig zoo li khoom noj khoom haus ntxiv. Tsis tas li ntawd, cov khoom no yog ib qho tseem ceeb rau neutralize acidic wastewater.
Magnesium yog dab tsi?
Magnesium yog cov tshuaj lom neeg muaj atomic naj npawb 12 thiab cov cim tshuaj Mg. Cov tshuaj no tshwm sim raws li ib tug grey-ci ci khoom nyob rau hauv chav tsev kub. Nws yog nyob rau hauv pawg 2, lub sij hawm 3 nyob rau hauv lub periodic table. Yog li ntawd, peb tuaj yeem hu nws ua s-block keeb. Ntxiv mus, magnesium yog ib qho alkaline ntiaj teb hlau (pab pawg 2 tshuaj muaj npe hu ua alkaline ntiaj teb hlau). Lub teeb tsa hluav taws xob ntawm cov hlau no yog [Ne]3s2

Magnesium hlau yog ib qho tshuaj lom neeg ntau hauv lub ntiaj teb. Lawm, cov hlau no tshwm sim ua ke nrog lwm cov tshuaj. Tsis tas li ntawd, lub xeev oxidation ntawm magnesium yog +2. Cov hlau dawb yog cov reactive heev, tab sis peb tuaj yeem tsim nws ua cov khoom siv hluavtaws. Nws tuaj yeem hlawv, ua kom lub teeb ci heev. Peb hu nws lub teeb dawb ci ntsa iab. Peb tuaj yeem tau txais magnesium los ntawm electrolysis ntawm magnesium ntsev. Cov ntsev magnesium no tuaj yeem tau los ntawm brine.
Magnesium yog cov hlau hnyav, thiab nws muaj qhov qis tshaj plaws rau melting thiab boiling cov ntsiab lus ntawm alkaline ntiaj teb hlau. Cov hlau no tseem nkig thiab yooj yim undergoes tawg nrog rau shear bands. Thaum nws yog alloyed nrog aluminium, lub alloy yuav ductile heev.

Cov tshuaj tiv thaiv ntawm magnesium thiab dej tsis nrawm li calcium thiab lwm yam alkaline ntiaj teb hlau. Thaum peb submerge ib daim ntawm magnesium hauv dej, peb tuaj yeem pom cov npuas hydrogen tawm ntawm cov hlau. Txawm li cas los xij, cov tshuaj tiv thaiv nrawm nrog dej kub. Ntxiv mus, cov hlau no tuaj yeem ua rau cov kua qaub tawm sab nraud, xws li hydrochloric acid (HCl).
Qhov txawv ntawm Magnesia thiab Magnesium yog dab tsi?
Txawm hais tias cov ntsiab lus magnesia thiab magnesium suab zoo sib xws lawv yog ob nqe lus sib txawv nrog cov tshuaj sib txawv. Magnesia los yog mis nyuj ntawm magnesia yog magnesium hydroxide thaum magnesium yog cov tshuaj lom neeg muaj atomic tooj 12 thiab cov cim tshuaj Mg. Qhov sib txawv tseem ceeb ntawm magnesia thiab magnesium yog tias magnesia yog inorganic compound magnesium hydroxide thaum magnesium yog cov tshuaj lom neeg.
Tsis tas li ntawd, magnesia tuaj yeem tshwm sim ib txwm muaj raws li cov ntxhia brucite thaum magnesium tshwm sim hauv cov zaub mov xws li brucite, dolomite, carnalite, thiab lwm yam thiab feem ntau hauv dej hiav txwv thiab brine.
Cov hauv qab no infographic teev qhov sib txawv ntawm magnesia thiab magnesium hauv daim ntawv teev npe.
Summary – Magnesia vs Magnesium
Magnesia yog ib qho khoom ua los ntawm magnesium. Qhov sib txawv tseem ceeb ntawm magnesia thiab magnesium yog tias magnesia yog inorganic compound magnesium hydroxide whereas magnesium yog ib qho tshuaj lom neeg.
