The overall, balanced, spontaneous reaction occurring in this (standard) cell is:
Cr2O72−(aq) + 6Cl−(aq)
+ 14H+(aq) → 7H2O(l) + 2Cr3+(aq) +
3Cl2(g)
7H2O(l) + 2Cr3+(aq) + 3Cl2(g) →
Cr2O72−(aq) + 6Cl−(aq)
+ 14H+(aq)
7H2O(l) + 2Cr3+(aq) + Cl2(g) →
Cr2O72−(aq) + 2Cl−(aq)
+ 14H+(aq)
2Cr3+(aq) + 3Cl2(g) →
Cr2O72−(aq) +
6Cl−(aq)
False True The solution in tube 'H' must not contain an
electrolyte for the cell to operate.
False True Tube 'H' allows Cr3+ ions to
migrate readily to the other compartment and to react directly with
the chlorine gas.
False True The salt bridge disrupts the electrical
circuit while permitting mixing of the solutions in the anode and
cathode compartments.
False True The salt bridge is intended to prevent
counter ions from flowing between the two cell compartments.
False True The salt bridge is labeled 'H'.
