Question

A sodium salt on treatment with M g C l 2 gives white precipitate only on heating. The anion of the sodium salt is, C O 3 2 -, S O 4 2 -, N O 3 -, H C O 3 -

MARKS App · Accepted Answer

Since magnesium bicarbonate on heating gives insoluble magnesium carbonate, therefore, the anion is H C O 3 - M g C l 2 + 2 N a H C O 3 → M g ( H C O 3 ) 2 S o l u b l e + 2 N a C l Mg ( HCO 3 ) 2 → Δ MgCO 3 White ↓ + H 2 O + CO 2 ↑
