    A Hydrogen ion always has an oxidation number of +1

    Thus NH4+ => [N + (4x +1) ] = +1; Thus N = -3

    An oxygen atom always has an oxidation state of -2

    OCl- => -2+ Cl = -1; Thus Cl = +1

    here's what i can remember from chem, hope this helps.

    a) N + 4H = +1

    N + 4(1) = 1

    N = -3

    b) O + Cl = -1

    -2 + Cl = -1

    Cl = 1

    I think it's 1 for N and 8 for Cl- but could be wrong

    a) -3

    b)+1
