Zinc sulfate, tare da dabarar sinadarai ta ZnSO4, wani lu'ulu'u ne mai launin rhombic mara launi tare da yawan 3.54. Yana rikidewa zuwa zinc oxide idan aka dumama shi zuwa 770℃. Ruwan da ke cikinsa shine zinc sulfate monohydrate ZnSO4·H2O, wani farin lu'ulu'u ne mai launin 3.31. Idan aka dumama shi zuwa 280℃, yana rasa ruwa kuma ya zama mara ruwa. Zinc sulfate hexahydrate ZnSO4·6H2O lu'ulu'u ne mai launin monoclinic ko tetragonal tare da yawan 2.07. Idan aka dumama shi zuwa 70℃, yana rasa kwayoyin ruwa guda 5 na crystallization don ya zama zinc sulfate monohydrate. Zinc sulfate heptahydrate, ZnSO4·7H2O, wanda aka fi sani da "alum" ko "zinc alum", shine nau'in da aka fi sani. Shi lu'ulu'u ne mai launin rhombic ko farin lu'ulu'u. Yana ratsawa a hankali a cikin busasshiyar iska, tare da yawan 1.96. A digiri 39, yana rasa kwayar halitta guda ɗaya ta ruwan kristal don ya zama zinc sulfate hexahydrate. Zinc sulfate yana narkewa sosai a cikin ruwa, kuma ruwan da ke cikinsa yana da ɗan acidic. Yana iya narkewa a cikin glycerol kuma yana narkewa kaɗan a cikin ethanol. Yana samar da gishiri biyu na nau'in ZnSO4·K2SO4·6H2O tare da potassium sulfate. Lokacin da aka narkar da zinc oxide na ƙarfe a cikin diluted sulfuric acid kuma aka tattara kuma aka lulluɓe shi a digiri 30, ana iya samun heptahydrate zinc sulfate. Sannan, ta hanyar ɗaga zafin jiki, ana iya samun wasu nau'ikan zinc sulfate daban-daban. Ana amfani da shi azaman mordant a rini da bugawa, mai kiyaye itace, wakili mai bleaching a cikin yin takarda, kuma ana amfani da shi a magani, zaruruwan wucin gadi, electrolysis, electroplating, magungunan kashe ƙwari da samar da gishirin zinc, da sauransu.

zinc sulfate ZnSO4, wanda aka fi sani da alum ko zinc alum, wani lu'ulu'u ne mai launin ko foda mara launi ko fari a zafin ɗaki. Yana da kaddarorin astringent, yana narkewa sosai a cikin ruwa, kuma ruwan da ke cikinsa yana da acidic. Yana narkewa kaɗan a cikin ethanol da glycerol. Sinadarin zinc sulfate mai tsarki baya canzawa zuwa rawaya lokacin da aka adana a cikin iska na dogon lokaci. Idan aka sanya shi a cikin busasshiyar iska, yana rasa ruwa kuma ya zama farin foda. Akwai nau'ikan hydrates daban-daban: sigar hydrate a cikin daidaito da ruwa a cikin kewayon 0-39℃ shine zinc sulfate heptahydrate; a cikin 39-60℃, zinc sulfate hexahydrate ne; kuma a cikin 60-100℃, zinc sulfate monohydrate ne. Idan aka dumama shi zuwa 280℃, duk hydrates suna rasa ruwan kristal ɗinsu gaba ɗaya. A 680℃, suna narkewa zuwa zinc oxysulfate. Sama da 750℃, suna ƙara ruɓewa. A ƙarshe, a kusan 930℃, suna ruɓewa zuwa zinc oxide da sulfur trioxide. ZnSO4·7H2O da MSO4·7H2O (M = Mg, Fe, Mn, Co, Ni) suna samar da lu'ulu'u masu gauraya a cikin wani takamaiman tsari.
