Which one is the most stable carbonate? * (a) BaCO3 (b) MgCO3 (c) CaCO3 (d) BeCO3 |
|
Answer» RONG>(a)BaCO3 BaCO3 is more thermally stable because polarising power of Ba2+ is less than other ALKALINE earth metals and thermal stability is inversely proportional to polarising power of action when compound containing polyatomic ANION and here carbonate is polyatomic anion. |
