When did organ music become associated with baseball? H3PO2-----PH3 change in oxidation number is from 1 to -3 .Thus 4e- are used from 2H3PO2 ----2H3PO2 Change in oxidation number is from 1 to +3 therefore electron given is 2e-.for 2 moleculae of H3PO2 thus 4 lectron are used thus in total 4e- are exchanged n factor=no of electron/no of mole=4/3 That it could be also +5 in of mice and men hypophosphite complex.!
