Vedclass · Answer

(B) In qualitative inorganic analysis,the group $III$ cations are precipitated as hydroxides using $NH_4Cl$ and $NH_4OH$ (aqueous $NH_3$).$Al^{3+}$ belongs to group $III$ and forms $Al(OH)_3$ precipitate in the presence of these reagents.$Ca^{2+}$ is a group $V$ cation,$Mg^{2+}$ is a group $VI$ cation,and $Zn^{2+}$ is a group $III$ cation but it is usually precipitated with $H_2S$ in the presence of $NH_4OH$ (group $III$ $B$). However,$Al^{3+}$ is the standard representative for group $III$ $A$ precipitation by $NH_4OH$.

Which ion is precipitated by the reagent $NH_4Cl$ and aqueous $NH_3$?
