Vedclass · Answer

(A) In $Na_2O_2$ (sodium peroxide),oxygen exists as a peroxide ion,$O_2^{2-}$,where the oxidation state of each oxygen atom is $-1$. Let the oxidation state of sodium be $x$. Applying the rule that the sum of oxidation states in a neutral molecule is $0$: $2(x) + 2(-1) = 0$ $2x - 2 = 0$ $2x = 2$ $x = +1$. Therefore,the oxidation state of sodium in $Na_2O_2$ is $+1$.

Find the oxidation state of sodium in $Na_2O_2$.
