The electrolytic cells, one containing acidified ferrous chloride and another acidified ferric chloride are connected in series. The ratio of iron deposited at cathodes in the two cells when electricity is passed through the cells will be:
Show Hint
- 3:1
- 2:1
- 1:1
- 3:2
The Correct Option is D
Solution and Explanation
Step 1: Use the relation for electrolysis.
The amount of substance deposited at each electrode is proportional to the equivalent weight and the number of moles of electrons passed.
Step 2: Conclusion.
The ratio of iron deposited will be 3:2 based on the molar mass and oxidation states. Final Answer: \[ \boxed{3:2} \]
