Question

When iron fillings are added to copper sulphate solution $Cu$ is precipitated because of:

• A. reduction of $Fe$
• B. oxidation of $Fe$
• C. reduction of sulphate ions
• D. hydrolysis of copper

Answer 1

The correct option is B oxidation of $Fe$

Iron is more reactive than copper and copper is displaced to form ferrous sulphate solution. So iron is oxidised as it losses electrons.
