Question

Compare the solubility and thermal stability of alkali metals carbonates with those of the alkaline earth metals nitrates.

Answer 1

Thermal stability ofAlkaline earth metal nitrate ---Alkaline earth metal nitrate decompose on heating.All alkaline earth metals Nitrates decompose to form metal oxide, $N{O}_2$ and $O_2$.

Thermal stability of alkali metal carbonate---- alkali metals carbonates are stable and do not decompose even at high temperature.

solubility of alkaline earth metal nitrates --Nitrates, of alkaline earth metals are soluble in water.thier solubility, however decreases as we move down the group because their hydration energies decreases more rapidly than the lattice energies.

Solubility of alkali metal carbonates ----alkali metals carbonates are soluble in water. Their solubility however increases as we move down the group since the lattice energies decreases more rapidly than the hydration energies.
