Which of the following metals will displace copper from copper sulfate solution?
Platinum
Silver
Iron
Gold
Iron
Iron is a more reactive metal than copper, which allows it to displace copper from its salt solution through a displacement reaction. This process is governed by the reactivity series of metals, where a higher-positioned metal displaces a lower-positioned metal from its aqueous salt solution.

Think of it like a stronger student (Iron) coming into a classroom and taking the seat occupied by a weaker student (Copper), forcing the weaker student to move out of their position.
Please Stop Calling Me A Careless Zebra Instead Try Learning How Copper Saves Gold (Potassium, Sodium, Calcium, Magnesium, Aluminum, Carbon, Zinc, Iron, Tin, Lead, Hydrogen, Copper, Silver, Gold).
Fe+CuSO4тАЛтЖТFeSO4тАЛ+Cu тАФ Chemical equation for displacement
The reaction follows the principle of Single Displacement: Fe(s)+CuSO4тАЛ(aq)тЖТFeSO4тАЛ(aq)+Cu(s). Because iron has a higher reduction potential (lower reactivity index) than copper, it readily loses electrons to form Fe2+ ions, while Cu2+ ions gain electrons to precipitate as metallic copper.
A more reactive metal displaces a less reactive metal.
Iron is more reactive than copper.
The blue color of copper sulfate fades as iron sulfate (light green) is formed.
Used in extractive metallurgy for metal recovery.
Extraction of metals from ores.
Purification of metal salts.
Gold, Silver, and Platinum are located below Copper in the reactivity series, hence they cannot displace Copper.
Reactivity series is established based on the ease of oxidation of the metals.
C is correct тАФ Iron is more reactive than copper in the metal reactivity series, allowing it to displace copper from the aqueous sulfate solution.
Remember that any metal higher than Hydrogen can displace it from acids, and any metal higher in the series can displace those below it from salt solutions.
