$Cs_2CO_3$

Vedclass · Answer

(A) The thermal stability of alkali metal carbonates increases as we move down the group from $Li_2CO_3$ to $Cs_2CO_3$. This is because the electropositive character of the alkali metal increases down the group,which increases the ionic character of the metal-oxygen bond. As the ionic character increases,the lattice energy and the stability of the carbonate ion increase. Therefore,$Cs_2CO_3$ has the highest thermal stability among the given options.

Among the carbonates of alkali metals,which one has the highest thermal stability?
