In the first step, Mn(OH)2 (s) is oxidized by gaseous oxygen to Mn(OH)3 (s) in basic aqueous solution. Write the oxidation and reduction half reactions for this step and write the balanced overall equation. From a table of standard reduction potentials, calculate the standard voltage that would be measured if this reaction were carried out in an electrochemical cell.
