Stability of alkali metal chlorides decreases down the group. As we move down group 1 and group 2, the thermal stability of nitrate increases. lattice enthalpy of ionic solid of cation of same valency having same anion decreases.It's due to down the group size of cation increases so attractive force between anion and cation … What is the trend in solubility of the group 2 nitrates, chlorides and sulphates? On heating, Beryllium nitrate forms nitrite and, other nitrates yield oxide, liberating brown fumes of nitrogen dioxide. Solubility of chlorides of alkali metal decrease down the group. A higher temperature is required to decompose Ba(NO 3) 2 as compared to Mg(NO 3) 2. … Solubility of BeSO 4 > MgSO 4 > CaSO 4 > SrSO 4 > BaSO 4 . Less attractions are formed … Magnesium carbonate (the most soluble Group 2 carbonate) has a solubility of about 0.02 g per 100 g of water at room temperature.
