Ukusetshenziswa
I-Zinc sulfate, enefomula yamakhemikhali i-ZnSO4, iyikristalu ye-rhombic engenambala enobukhulu obuyi-3.54. Iyabola ibe yi-zinc oxide uma ishiswa ku-770℃. I-hydrate yi-zinc sulfate monohydrate i-ZnSO4·H2O, ikristalu emhlophe ewuphuphu enobukhulu obuyi-3.31. Uma ishiswa ku-280℃, ilahlekelwa amanzi bese iba yi-anhydrous. I-Zinc sulfate hexahydrate i-ZnSO4·6H2O iyikristalu ye-monoclinic noma ye-tetragonal engenambala enobukhulu obuyi-2.07. Uma ishiswa ku-70℃, ilahlekelwa ama-molecule amanzi ayi-5 e-crystallization ukuze ibe yi-zinc sulfate monohydrate. I-Zinc sulfate heptahydrate, i-ZnSO4·7H2O, eyaziwa kakhulu ngokuthi "i-alum" noma "i-zinc alum", uhlobo oluvame kakhulu. Iyikristalu ye-rhombic engenambala noma i-white crystal powder. Iphuma kancane kancane emoyeni owomile, enobukhulu obuyi-1.96. Uma ishisa ngo-39℃, ilahlekelwa yi-molecule eyodwa yamanzi acwebezelayo ukuze ibe yi-zinc sulfate hexahydrate. I-Zinc sulfate incibilika kakhulu emanzini, futhi isixazululo sayo samanzi sinciphile kakhulu. Ingancibilika ku-glycerol futhi incibilika kancane ku-ethanol. Yakha usawoti ophindwe kabili wohlobo lwe-ZnSO4·K2SO4·6H2O nge-potassium sulfate. Lapho i-zinc metallic noma i-zinc oxide incibilika ku-dilute sulfuric acid futhi igxilile futhi icwebezela ku-30℃, i-heptahydrate zinc sulfate ingatholakala. Ngemuva kwalokho, ngokuphakamisa izinga lokushisa, kungatholakala ezinye izinhlobo ezahlukene ze-zinc sulfate. Isetshenziswa njenge-mordant ekudayiseni nasekunyatheliseni, isilondolozi sokhuni, i-bleaching agent ekwenzeni iphepha, futhi isetshenziswa nakwezokwelapha, imicu yokwenziwa, i-electrolysis, i-electroplating, izibulala-zinambuzane kanye nokukhiqizwa kosawoti be-zinc, njll.
I-zinc sulfate ZnSO4, eyaziwa nangokuthi i-alum noma i-zinc alum, iyikristalu noma i-powder engenambala noma emhlophe e-orthorhombic emazingeni okushisa asekamelweni. Inezakhiwo ezincibilikayo, incibilika kakhulu emanzini, futhi isixazululo sayo samanzi sine-acidic. Incibilika kancane ku-ethanol kanye ne-glycerol. I-zinc sulfate emsulwa ayiphenduki iphuzi uma igcinwe emoyeni isikhathi eside. Uma ifakwa emoyeni owomile, ilahlekelwa amanzi bese iba yi-powder emhlophe. Kunezinhlobo ezahlukene zama-hydrate: i-hydrate ezinzile elinganayo namanzi ngaphakathi kwebanga elingu-0-39℃ yi-zinc sulfate heptahydrate; ngaphakathi kuka-39-60℃, yi-zinc sulfate hexahydrate; futhi ngaphakathi kuka-60-100℃, yi-zinc sulfate monohydrate. Uma ishiswa ku-280℃, wonke ama-hydrate alahlekelwa ngokuphelele amanzi awo acwebezelayo. Ku-680℃, ayabola abe yi-zinc oxysulfate. Ngaphezu kuka-750℃, ayabola futhi. Ekugcineni, cishe ku-930℃, ayabola abe yi-zinc oxide kanye ne-sulfur trioxide. I-ZnSO4·7H2O kanye ne-MSO4·7H2O (M = Mg, Fe, Mn, Co, Ni) zakha amakristalu axubile ngaphakathi kobubanzi obuthile.
