  • 2. 

    A reduction reaction has taken place at electrode _______________.

    • A

    • B

    Correct Answer
    A. A
    Explanation
    A reduction reaction has taken place at electrode A.

    Rate this question:

  • 3. 

    The chloride ions are _______________ in the electrolysis reaction.

    • Reduced

    • Oxidized

    Correct Answer
    A. Oxidized
    Explanation
    In the electrolysis reaction, chloride ions are oxidized. This means that they lose electrons and undergo a chemical reaction in which their oxidation state increases. Oxidation occurs at the anode, where chloride ions give up their electrons to form chlorine gas. This process is essential for the overall reaction to occur, as it allows for the reduction of other species at the cathode.

  • 4. 

    Bromide ions would move towards electrode A

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Look at the cell properly. The longer line represents positive end of the battery.

    Rate this question:

  • 5. 

    The anode half equation is _______________.(a) 2Br-(l) --> Br2(g) + e(b) 2Br-(l) --> Br2(l) + 2e(c) Zn2+(l) + 2e--> Zn(s)(d) Zn2+(l) + 2e --> Zn(l)

    • (a)

    • (b)

    • (c)

    • (d)

    Correct Answer
    A. (a)
    Explanation
    The correct answer is (a) because it represents the oxidation of bromide ions (Br-) to bromine gas (Br2) and the release of an electron (e). This is consistent with the definition of an anode, which is the electrode where oxidation occurs.

    Rate this question:

  • 6. 

    The cathode half equation is _______________.(a) Br-(l) --> Br2(g) + e(b) 2Br-(l) --> Br2(l) + 2e(c) Zn2+(l) + 2e--> Zn(s)(d) Zn2+(l) + 2e --> Zn(l)

    • (a)

    • (b)

    • (c)

    • (d)

    Correct Answer
    A. (d)
    Explanation
    The correct answer is (d) because it represents the reduction half-reaction of zinc ions (Zn2+) being reduced to zinc (Zn) by gaining two electrons (2e-). This is consistent with the definition of a cathode, which is the electrode where reduction occurs in an electrochemical cell.
