Vedclass · Answer

(A) When a sodium bicarbonate $(NaHCO_3)$ solution is added to a magnesium salt solution (like $MgCl_2$),it forms magnesium bicarbonate: $MgCl_2 + 2NaHCO_3 	o Mg(HCO_3)_2 + 2NaCl$ Upon heating,magnesium bicarbonate decomposes to form a white precipitate of magnesium carbonate: $Mg(HCO_3)_2 \xrightarrow{\Delta} MgCO_3 \downarrow + H_2O + CO_2$ Therefore,the anion is bicarbonate $(HCO_3^-)$.
