Use the References A standard galvanic cell is constructed with Br₂ | Br and Mn2+ | Mn half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) Mn2+ is reduced at the cathode. The anode compartment is the Mn2+ | Mn compartment. As the cell runs, anions will migrate from the Br₂|Br compartment to the Mn2+1Mn compartment. In the external circuit, electrons flow from the Br₂ Br compartment to the Mn2+1Mn compartment. Mn is oxidized at the anode. Submit Answer Retry Entire Group 2 more group attempts remaining
Use the References to access important values if needed for this question. A standard galvanic cell is constructed in which a H+ | H₂ half cell acts as the cathode. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) In the external circuit, electrons flow from the other compartment to the H*|H₂ compartment. As the cell runs, anions will migrate from the other compartment to the H*|H₂ compartment. The cathode reaction is H₂ -> 2H+ + 2e². The anode compartment could be Cl₂|CI". OH+ is reduced at the cathode. Submit Answer Retry Entire Group 2 more group attempts remaining
Use the References to access important values if needed for this question. A standard galvanic cell is constructed with A13+|AI and Cr³+|Cr²+ half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) Al3+ is reduced at the cathode. The cathode compartment is the Cr³+1 Cr2+ compartment. 0 In the external circuit, electrons flow from the Al³+|AI compartment to the Cr³+ |Cr2+ compartment. As the cell runs, anions will migrate from the Al³+|AI compartment to the Cr³+|Cr2+ compartment. The anode compartment is the Cr³+|Cr2+ compartment.
