Number of Equivalents

NH_(3) is oxidised to NO by O_(2) (air) in basic medium. Number of equivalent of NH_(3) oxidised by 1 mol of O_(2) is :

Which has maximum number of equivalent per mole of the oxidant?

Statement The equivalence point refers the condition where equivalents of one species reacts with same number of equivalent of other species. Explanation The end point of titration is exactly equal to equivalence point.
