Displacement reaction between Iron And Copper Sulphate

When an iron nail is placed in a blue copper sulphate solution, a single displacement reaction occurs because iron is more reactive than copper. Chemical Equation: Fe(s)+CuSO4 (aq)----- FeSO4(aq)+Cu (s) Iron (Fe) displaces copper (Cu) from copper sulphate (CuSO4) to form iron(II) sulphate (FeSO4) and solid copper. Key Observations nail color change: The grey iron nail gets a reddish-brown coating of metallic copper. Solution color change: The solution turns from blue to light green due to the creation of ferrous sulphate (FeSO4). Why It Happens reactivity: Iron sits higher than copper on the metal reactivity series, meaning it loses electrons more easily. Electron transfer: Iron undergoes oxidation to form (Fe^2+) ions in the liquid, while (Cu^2+) ions undergo reduction to form solid copper on the nail.
