Vedclass · Answer

(A) The name sodium hexafluoroaluminate$(III)$ indicates the presence of sodium ions $(Na^+)$ and the complex anion hexafluoroaluminate$(III)$.In the complex anion $[AlF_6]^{n-}$,the oxidation state of $Al$ is $+3$ and each $F$ is $-1$.Therefore,the charge $n$ on the complex is calculated as: $x + 6(-1) = -3$,so $x = +3$.The complex ion is $[AlF_6]^{3-}$.To balance the charge of the complex ion,three $Na^+$ ions are required.Thus,the formula is $Na_3[AlF_6]$.

Which from the following is the formula of sodium hexafluoroaluminate$(III)$?
