Copper sulphate solution does not react with

Options

  1. AZinc
  2. BIron
  3. CSilver
  4. DAll of these

Correct answer

C. Silver

Step-by-step solution

C u S O 4 will react with elements placed above it in electrochemical series and it would not react with elements places below it in electrochemical series. ∴ C u S O 4 reacts with Zn and Fe placed above it. C u S O 4 + Fe → F e S O 4 + Cu C u S O 4 + Zn → Z n S O 4 + Cu ∴ C u S O 4 does not react with Ag, placed below it. C u S O 4 + Ag → no reaction.
