Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
What are the reactions of copper and zinc metal using concentrated nitric acid concentrated sulfuric acid potassium chloride solution and zinc powder metal?
When copper metal is reacted with concentrated nitric acid, it undergoes an oxidation reaction to form copper(II) nitrate, nitrogen dioxide gas, and water. When zinc metal is reacted with concentrated sulfuric acid, a displacement reaction occurs to form zinc sulfate and hydrogen gas. When a potassium chloride solution is reacted with zinc powder, a single displacement reaction takes place to form zinc chloride solution and potassium metal.
