Two electrolytic cells, one containing acidified ferrous chloride and...
Explanation:
When two electrolytic cells are connected in series, the total potential difference applied across the cells is equal to the sum of the potential differences of the individual cells. In this case, since the cells contain different electrolytes, the potential differences across the cells may be different.
Electrolytic Cells:
1. Acidified Ferrous Chloride Cell: Fe^2+ + 2e^- -> Fe
2. Acidified Ferric Chloride Cell: Fe^3+ + 3e^- -> Fe
Explanation of the given Options:
a) 3:1 - This ratio implies that for every 3 moles of iron deposited in the acidified ferrous chloride cell, 1 mole of iron is deposited in the acidified ferric chloride cell. However, this ratio does not hold true based on the reactions mentioned above. Therefore, option a) is incorrect.
b) 2:1 - This ratio implies that for every 2 moles of iron deposited in the acidified ferrous chloride cell, 1 mole of iron is deposited in the acidified ferric chloride cell. Again, this ratio does not hold true based on the reactions mentioned above. Therefore, option b) is incorrect.
c) 1:1 - This ratio implies that the same amount of iron is deposited in both the acidified ferrous chloride and acidified ferric chloride cells. This ratio is also inconsistent with the reactions mentioned above. Therefore, option c) is incorrect.
d) 3:2 - This ratio implies that for every 3 moles of iron deposited in the acidified ferrous chloride cell, 2 moles of iron are deposited in the acidified ferric chloride cell. This ratio is consistent with the reactions mentioned above. Therefore, option d) is the correct answer.
Conclusion:
The correct answer is option d) 3:2. For every 3 moles of iron deposited in the acidified ferrous chloride cell, 2 moles of iron are deposited in the acidified ferric chloride cell when the cells are connected in series.
