How are zinc chloride crystals produced
WebDescribe how zinc chloride crystals are produced from zinc chloride solution. [2 marks] Sulfuric acid and sodium hydroxide react to produce sodium sulfate. 0 4 . 6 Sulfuric acid is gradually added to sodium hydroxide solution. The pH of the mixture changes as the sulfuric acid is added until in excess. Suggest the pH at: WebZinc nitrate is usually prepared by dissolving zinc metal, zinc oxide, or related materials in nitric acid : Zn + 2 HNO3 → Zn (NO3)2 + H2 ZnO + 2 HNO3 → Zn (NO3)2 + H2O These reactions are accompanied by the hydration of the zinc nitrate. The anhydrous salt arises by the reaction of anhydrous zinc chloride with nitrogen dioxide: [1]
