a sodium salt on treatment with mgci2 gives white

A sodium salt on treatment with $$MgC{l_2}$$ gives white precipitate only on heating. The anion of the sodium salt is

A. $$HCO_3^ - $$

B. $$CO_3^{2 - }$$

C. $$NO_3^ - $$

D. $$SO_4^{2 - }$$

Answer : $$HCO_3^ - $$

Solution :
$$MgC{l_2} + 2NaHC{O_3} \to \mathop {MgHC{O_3}}\limits_{\left( {{\text{soluble}}} \right)} + 2NaCl$$
\[MgHC{{O}_{3}}\xrightarrow{\text{heat}}MgC{{O}_{3}}\downarrow +{{H}_{2}}O+C{{O}_{2}}\]
