Vedclass · Answer

(A) The name pentaaquanitratochromium$(III)$ nitrate indicates the following components: $1$. The central metal ion is Chromium $(Cr)$ with an oxidation state of $+3$. $2$. The ligands are five water molecules ($H_2O$,aqua) and one nitrate ion ($NO_3^-$,nitrato). $3$. The coordination sphere is $[Cr(H_2O)_5(NO_3)]$. $4$. To balance the charge: $Cr$ is $+3$,$H_2O$ is $0$,and $NO_3$ is $-1$. The net charge on the coordination sphere is $(+3) + 0 + (-1) = +2$. $5$. To neutralize the $+2$ charge of the complex,two nitrate ions $(NO_3^-)$ are required outside the coordination sphere. $6$. Thus,the formula is $[Cr(H_2O)_5(NO_3)](NO_3)_2$.

The formula of pentaaquanitratochromium$(III)$ nitrate is,
