Vedclass · Answer

(A) The compound is $Ba(H_2PO_2)_2$. Let the oxidation number of $P$ be $x$. The oxidation number of $Ba$ is $+2$,$H$ is $+1$,and $O$ is $-2$. Setting the sum of oxidation numbers to $0$: $+2 + 2 	imes [2 	imes (+1) + x + 2 	imes (-2)] = 0$ $+2 + 2 	imes [2 + x - 4] = 0$ $+2 + 2 	imes [x - 2] = 0$ $2 + 2x - 4 = 0$ $2x - 2 = 0$ $2x = 2$ $x = +1$. Therefore,the oxidation number of $P$ is $+1$.
