Question
Among the carbonates of alkali metals which one has highest thermal stability?Cs2CO3Rb2CO3K2CO3Na2CO3
Solution
The thermal stability of alkali metal carbonates increases down the group in the periodic table. This is because as the size of the alkali metal cation increases, it can stabilize the larger carbonate anion more effectively. Therefore, among the given options, Cs2CO3 (Cesium carbonate) has the highest thermal stability.
