Scene 2

1) Solubility of Carbonates & Sulphates :

Thermal stability of Carbonates and Nitrates :. Δ. 

Scene 3

Thermal stability of Carbonates and Nitrates :

Carbonates & nitrates of alkaline earth metals on heating decomposes as;
 MC
 M   MO + C  
 MO + N

Polarization ; The distoration in anion due to the presence of cation is called polarization. Higher the polarizing power of cation lower will be the stability of that compounds.
