Vedclass · Answer

(A) In the systematic qualitative analysis of basic radicals,the $V$ group radicals $(Ca^{2+}, Ba^{2+}, Sr^{2+})$ are precipitated as carbonates using $(NH_4)_2CO_3$ in the presence of $NH_4Cl$ and $NH_4OH$. $Mg^{2+}$ does not precipitate with $(NH_4)_2CO_3$ in the presence of $NH_4Cl$ and $NH_4OH$ because the concentration of carbonate ions is suppressed by the common ion effect,and $MgCO_3$ is relatively more soluble. Therefore,only $Ca^{2+}, Ba^{2+}, Sr^{2+}$ are precipitated.

Which radicals are precipitated by $(NH_4)_2CO_3$ in the presence of $NH_4OH$ (alkali)?
