WebAug 15, 2024 · Pure zinc is a bluish-silver and ductile metal with a low melting and boiling point. Most zinc today is obtained from ZnS, extracted from zinc blende ore and roasted to remove the sulfur. Zinc can also be obtained by electrolysis of aqueous zinc sulfate, a common laboratory exercise. Zinc plays a huge part in the production of alloys. WebThe order of reactivity is: magnesium > zinc > copper. This is because magnesium could displace copper and zinc, zinc could only displace copper, but copper could not displace magnesium or...

Characteristic reactions of Zn²⁺ Zinc (II) ion forms complex ions readily. Aqueous Ammonia Zinc (II) ion reacts with aqueous ammonia to precipitate white gelatinous Zn (OH)2: WebZinc sulfate is formed and iron is displaced. It’s a “displacement reaction”: Zn + FeSO4•H2O = ZnSO4 + Fe + H2O (l) Change in Free Energy: ΔG (20C) = -26.6kJ (negative, so the reaction runs) Change in Enthalpy: ΔH (20C) = -24.4kJ (negative, so the reaction is exothermic) 3 Abhishek Kumar 4 y Related cyst of face
