Oxidation numbers of P in P O_4^3−, of S in S O_4^2− and that of Cr in C r_2O_7^2− are respectively

Question

Accepted Answer

Correct answer: D. (d) Let oxidation number of PinP O_4^3− be x.x+4_(−2_)=−3=x=+5 Let oxidation number of SinS O_4^2− be y. y+4_(−2_)=−2=y=+6 Let oxidation number of Cr in C r_2O_7^2− be z. 2 z+7_(−2_)=−2=z=+6

$Oxidation numbers of P in P O_{4}^{3 -}, of S in S O_{4}^{2 -} and that of Cr in C r_{2} O_{7}^{2 -} are respectively$
