Magnesium sulfate
Ib qho chaw uas muaj magnesium, feem ntau siv tshuaj thiab ziab khaub ncaws, suav nrog magnesium cation Mg2 + (20.19% los ntawm pawg) thiab sulfate anion SO2-4.Dawb crystalline khoom, soluble hauv dej, insoluble hauv ethanol.Feem ntau ntsib nyob rau hauv daim ntawv ntawm hydrate MgSO4·nH2O, rau ntau yam n qhov tseem ceeb ntawm 1 thiab 11. Feem ntau yog MgSO4·7H2O.

Sodium Bisulfate
Sodium bisulphate, tseem hu ua sodium acid sulfate, yog sodium chloride (ntsev) thiab sulfuric acid tuaj yeem hnov mob ntawm qhov kub thiab txias los tsim cov khoom, cov tshuaj anhydrous muaj hygroscopic, aqueous kua yog acidic.Nws yog ib tug muaj zog electrolyte, kiag li ionized nyob rau hauv lub molten lub xeev, ionized rau hauv sodium ions thiab bisulfate.Hydrogen sulfate tuaj yeem tsuas yog tus kheej-ionization, ionization equilibrium tas li me me, tsis tuaj yeem ua tiav ionized.

Ferrous Sulfate
Ferrous sulfate yog ib yam khoom tsis muaj zog, cov crystalline hydrate yog heptahydrate ntawm qhov kub thiab txias, feem ntau hu ua "ntsuab alum", lub teeb ntsuab siv lead ua, huab cua qhuav, qhov chaw oxidation ntawm xim av yooj yim hlau sulfate nyob rau hauv cov huab cua ntub, ntawm 56.6 ℃ los ua tetrahydrate, ntawm 65 ℃ los ua monohydrate.Ferrous sulfate yog soluble hauv dej thiab yuav luag insoluble hauv ethanol.Nws cov tshuaj aqueous oxidizes maj mam hauv huab cua thaum nws txias, thiab oxidizes sai dua thaum nws kub.Ntxiv alkali lossis raug rau lub teeb tuaj yeem ua kom nws oxidation.Tus txheeb ze ntom ntom (d15) yog 1.897.

Magnesium Chloride
Cov tshuaj inorganic uas yog tsim los ntawm 74.54% chlorine thiab 25.48% magnesium thiab feem ntau muaj rau lub molecules ntawm crystalline dej, MgCl2.6H2O.Monoclinic crystal, los yog qab ntsev, muaj qee yam corrosive.Magnesium oxide yog tsim thaum dej thiab hydrogen chloride poob thaum cua sov.Me ntsis soluble hauv acetone, soluble hauv dej, ethanol, methanol, pyridine.Nws deliqueses thiab ua rau cov pa luam yeeb hauv huab cua ntub, thiab sublimates thaum nws kub kub hauv cov pa roj hydrogen.
