Answer» SOLUTION :(i) Let the oxidation state of P be x. `{:((i),overset(+1)(H_(3))overset(x)(P)overset(-2)(O_(3))" "therefore" "3(+1)+x+3(-2)=0 or x = +3,(ii),overset(x)(P)overset(-1)(Cl_(3))" "therefore" "x+3(-1)=0 or x = +3),((iii),overset(+2)(Ca_(3))overset(x)(P_(2))""therefore" "3(+2)+2 xx x = 0 or x = -3,(iv),overset(+1)(Na_(3))overset(x)(P)overset(-2)(O_(4))" "therefore""3(+1)+x+4(-2)=0 or x = +5),((V),overset(x)(P)overset(-2)(O)overset(-1)(F_(3))" "therefore" "x + 1 (-2)+3(-1)=0 or x = +5,,):}` |
