    i need help on writing redox reactions and with finding the electrode in oxidization and in reduction. oh and what are the three conditions under which the voltmeter reading will be 0 (zero)?
    THANKS:biggrin:

    Please show some effort in answer the questions yourself.

    With regard to the three conditions under which the voltmeter reading will be 0, obviously the voltmeter reads zero with a zero potential across the terminals, which would be the case if the two electrodes were equal.

    Think of how a voltmeter works.

    I would expect that one's textbook would explain redox reactions and half-cell potentials.

    These might be useful -
