Q. The carbonate that will not decompose on heating is
A) $Na_{2}CO_{3}$
B) $CaCO_{3}$
C) $BaCO_{3}$
D) $SrCO_{3}$
Explanation
(a)
$Na_{2}CO_{3}$will not decompose on heating.
All alkali metal (IA group) carbonates (except $Li_{2}CO_{3}$) are highly stable and not decomposes on heating. Carbonates of alkaline earth metals (II A group) decompose into $CO_{2}$ and metal oxide.
