A galvanic cell based on the above reaction is constructed according to the generic sketch of a galvanic cell shown below:
E B F 1 D H G
Choose the label which best describes the following: ✰ Direction which cations move through the salt bridge Pt anode The overall, balanced, spontaneous reaction occurring in this (standard) cell is: O 7H₂0(1) + 2Cr³+ (aq) + Cl₂(g) → Cr₂O72-(aq) + 2Cl(aq) + 14H+ (aq) O Cr₂O7²-(aq) + 6CI¯(aq) + 14H+ (aq) → 7H₂O(1) + 2Cr³+ (aq) + 3Cl₂(g) O 7H₂0(1) + 2Cr³+ (aq) + 3Cl2(g) → Cr₂O72-(aq) + 6CI (aq) + 14H+ (aq) O 2Cr³+ (aq) + 3Cl₂(g) → Cr₂O72-(aq) + 6Cl(aq) The salt bridge completes the electrical circuit while separating the anode and cathode compartments. Tube 'F' hinders Cr³+ ions from migrating to the compartment and reacting directly with the chlorine other gas. The salt bridge is intended to allow counter ions to flow between the two cell compartments. The solution in tube 'F' must contain an electrolyte for the cell to operate. The salt bridge is labeled 'B'.
