$Zn^{2+}, Al^{3+}$

Vedclass · Answer

(A) $Zn^{2+}$ forms a coordination compound with both aqueous sodium hydroxide and ammonia,while $Al^{3+}$ forms a coordination compound only with aqueous sodium hydroxide.Zinc forms the tetrahydroxozincate$(II)$ complex with $NaOH$: $Zn^{2+} + 4OH^{-} \rightarrow [Zn(OH)_{4}]^{2-}$.Zinc forms the tetraamminezinc$(II)$ complex with $NH_{3}$: $Zn^{2+} + 4NH_{3(aq)} \rightarrow [Zn(NH_{3})_{4}]^{2+}$.Aluminum forms the hexahydroxoaluminate$(III)$ complex with aqueous sodium hydroxide: $Al^{3+} + 6OH^{-} \rightarrow [Al(OH)_{6}]^{3-}$.Aluminum does not form a coordination compound with aqueous ammonia.

In which one of the following pairs of ions is there an ion that forms a coordination compound with both aqueous sodium hydroxide and ammonia,and another ion that forms a coordination compound only with aqueous sodium hydroxide?
