D is very correct 💯💯💯💯💥💥💥

Fe + CuSO₄ ===> Cu + FeSO₄

✨ The metal that is use for recovering copper from copper sulphate should be a stronger reducing agent than the copper and should not react with water🤝🤝🤝🤝🤝🤝🤝

Sodium metal reacts with water and will form sodium hydroxide and will not be able to reduce the copper from copper sulphate 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

Mercury and Silver can not be used to displace copper from the copper sulphate solution because Mercury and Silver are less easily oxidized than copper🤝🤝🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️🏋️

The correct answer is:

C. Copper(II) oxide (CuO)

Explanation:
Copper turnings (A): Copper metal does not react with dilute H₂SO₄ under normal conditions because it is below hydrogen in the electrochemical series and does not displace hydrogen from acids.
Copper(II) trioxocarbonate(IV) (B): CuCO₃ reacts with dilute H₂SO₄, but it produces effervescence due to the release of CO₂ gas.
Copper(II) oxide (C): CuO dissolves in warm dilute H₂SO₄ without effervescence to form blue copper(II) sulfate (CuSO₄):
Copper alloy (D): Alloys contain copper mixed with other metals (e.g., brass, bronze), and their reaction with dilute H₂SO₄ depends on the composition. However, most alloys resist reaction under normal conditions.
Since only CuO dissolves in warm, dilute H₂SO₄ without gas evolution while giving a blue solution, C is the correct answer.
