Wadannan hadaddun suna da iyakancewar solubility a cikin ruwa, ta haka ne ke ƙara yawan solubility naazurfa sulfate.
The reactivity naazurfa sulfatea cikin ruwa bai iyakance ga halin rushewar sa ba. Hakanan yana jurewa halayen redox masu ban sha'awa. Misali, idan an ƙara zinc na ƙarfe a cikin wani bayani mai ɗauke da shiazurfa sulfate, yanayin ƙaura yana faruwa.
