Ukusetyenziswa
I-Zinc sulfate, enefomyula yekhemikhali i-ZnSO4, yikristale ye-rhombic engenambala enobunzima obuyi-3.54. Iyabola ibe yi-zinc oxide xa ifudunyezwa ukuya kwi-770℃. I-hydrate yi-zinc sulfate monohydrate i-ZnSO4·H2O, ikristale emhlophe engumgutyulo enobunzima obuyi-3.31. Xa ifudunyezwa ukuya kwi-280℃, ilahlekelwa ngamanzi kwaye ibe yi-anhydrous. I-Zinc sulfate hexahydrate i-ZnSO4·6H2O yikristale ye-monoclinic okanye ye-tetragonal engenambala enobunzima obuyi-2.07. Xa ifudunyezwa ukuya kwi-70℃, ilahlekelwa ziimolekyuli ezi-5 zamanzi e-crystallization ibe yi-zinc sulfate monohydrate. I-Zinc sulfate heptahydrate, i-ZnSO4·7H2O, eyaziwa ngokuba yi-"alum" okanye "zinc alum", lolona hlobo luqhelekileyo. Yikristale ye-rhombic engenambala okanye umgubo wekristale emhlophe. Iphuma kancinci kancinci emoyeni owomileyo, enobunzima obuyi-1.96. Kwi-39℃, ilahlekelwa yimolekyuli enye yamanzi ekristale ukuze ibe yi-zinc sulfate hexahydrate. I-Zinc sulfate iyanyibilika kakhulu emanzini, kwaye isisombululo sayo samanzi sincinci kakhulu. Inokunyibilika kwi-glycerol kwaye iyanyibilika kancinci kwi-ethanol. Yenza ityuwa ephindwe kabini yohlobo lwe-ZnSO4·K2SO4·6H2O ene-potassium sulfate. Xa i-zinc yesinyithi okanye i-zinc oxide inyibilika kwi-dilute sulfuric acid kwaye igxininiswe kwaye ikristale kwi-30℃, i-heptahydrate zinc sulfate inokufumaneka. Emva koko, ngokunyusa ubushushu, ezinye iintlobo ezahlukeneyo ze-zinc sulfate zinokufunyanwa. Isetyenziswa njenge-mordant ekudayini nasekuprinteni, isigcini somthi, i-agent yokumhlopheza ekwenzeni iphepha, kwaye ikwasetyenziswa kumayeza, kwiifayibha zokwenziwa, kwi-electrolysis, kwi-electroplating, kwiipesticides nakwimveliso yeetyuwa ze-zinc, njl.
I-zinc sulfate ZnSO4, ekwaziwa ngokuba yi-alum okanye i-zinc alum, yikristale okanye umgubo omhlophe ongenambala okanye omhlophe ofana ne-orthorhombic kubushushu begumbi. Ineempawu zokurhawuzelela, iyanyibilika kakhulu emanzini, kwaye isisombululo sayo samanzi sine-asidi. Iyanyibilika kancinci kwi-ethanol kunye ne-glycerol. I-zinc sulfate ecocekileyo ayitshintshi ibe tyheli xa igcinwe emoyeni ixesha elide. Xa ibekwe emoyeni owomileyo, ilahlekelwa ngamanzi kwaye ibe ngumgubo omhlophe. Kukho ii-hydrate ezahlukeneyo: i-hydrate ezinzileyo elinganayo namanzi ngaphakathi koluhlu lwe-0-39℃ yi-zinc sulfate heptahydrate; ngaphakathi kwe-39-60℃, yi-zinc sulfate hexahydrate; kwaye ngaphakathi kwe-60-100℃, yi-zinc sulfate monohydrate. Xa ishushu ukuya kwi-280℃, zonke ii-hydrate zilahlekelwa ngokupheleleyo ngamanzi azo ekristale. Kwi-680℃, ziyabola zibe yi-zinc oxysulfate. Ngaphezulu kwe-750℃, ziyabola ngakumbi. Ekugqibeleni, malunga ne-930℃, ziyabola zibe yi-zinc oxide kunye ne-sulfur trioxide. I-ZnSO4·7H2O kunye ne-MSO4·7H2O (M = Mg, Fe, Mn, Co, Ni) zenza iikristale ezixutyiweyo ngaphakathi koluhlu oluthile.
