Question

If a spoon of copper metal is placed in a solution of ferrous sulphate

• A. Cu will precipitate out
• B. Iron will precipitate
• C. Cu and Fe will precipitate
• D. no reaction will take place

Answer 1

Answer: (D)

no reaction will take place

Answer 2

$E_{Cu^{2 +}/Cu}^{0} = 0.34E_{Fe^{2 +}/Fe}^{0} = - 0.44volt$

So Cu can't displace Fe2+
