Vedclass · Answer

(A) The oxidation state of $K$ is $+1$ and the oxalate ion $(C_{2}O_{4}^{2-})$ has a charge of $-2$. Let the oxidation state of $Cr$ be $x$. For the complex $K_{3}[Cr(C_{2}O_{4})_{3}]$,the sum of oxidation states is zero: $(3 	imes (+1)) + x + (3 	imes (-2)) = 0$ $3 + x - 6 = 0$ $x - 3 = 0$ $x = +3$ Therefore,the oxidation state of $Cr$ is $+3$.

Identify the oxidation state of $Cr$ in $K_{3}[Cr(C_{2}O_{4})_{3}]$.
