Which of the following order is correct for with respect to indicate property?

Question

TestHub · Accepted Answer

The correct order for thermal stability is $N a_{2} C O_{3} > A g_{2} C O_{3}$ . Alkali metal carbonates are generally more thermally stable than transition metal carbonates due to stronger ionic bonding and larger cation size, which stabilizes the carbonate anion.

Explanation for other options:

A. Solubility in water: $KHC O_{3} > NaHC O_{3}$ (Potassium salts are generally more soluble than sodium salts).

B. Basic strength: $T l_{2} O_{3} > G a_{2} O_{3}$ (Basic strength increases down the group for oxides of the same oxidation state).

C. Solubility in organic solvent: $LiCl > LiF$ (LiCl has more covalent character and is more soluble in organic solvents than LiF).
