In salts of polyatomic anion, as polarising power of cation increases, thermal stability of the salt — d and f Block Elements Chemistry Question
Question
In salts of polyatomic anion, as polarising power of cation increases, thermal stability of the salt decreases and decomposed species may further undergo redox reaction. [1]
Answer: D
💡 Solution & Explanation
2FeSO4 $\xrightarrow{\Delta}$ Fe2O3 + SO2$\uparrow$ + SO3$\uparrow$<br>SnSO4 $\xrightarrow{\Delta}$ SnO2 + SO2$\uparrow$<br>H2C2O4 $\xrightarrow{\Delta}$ CO$\uparrow$ + CO2$\uparrow$ + H2O<br>2Na2HPO4 $\xrightarrow{\Delta}$ Na4P2O7 + H2O [2]
