The sulphates become less soluble as you go down the Group. The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.Units of solubility are given in grams per 100 millilitres of water (g/100 ml), unless shown otherwise. (iii) Sulphates. Sulphates of alkali metals are soluble in water. A question asking about the solubility of the Group 2 sulphates would probably ask you to state and explain the trend in solubilities of the sulphates of Group 2 elements. Since the hydration enthalpy decreases faster than the lattice enthalpy in the case of Group 2 sulphates, the solubility of Group 2 sulphates decreases while progressing down the group. Group 2 carbonates are virtually insoluble in water. SOLUBILITY OF COMPOUNDS (GROUP 1) Solubility of a compound mainly depends on two factors . A saturated solution has a concentration of about 1.3 g per 100 g of water at 20°C. Barium hydroxide is soluble enough to be able to produce a solution with a concentration of around 0.1 mol dm-3 at room temperature. Again, the hydration enthalpy decreases the same way as it does in the case of Group 2 cations bonded to OH⁻ ions. Magnesium carbonate (the most soluble Group 2 carbonate) has a solubility of about 0.02 g per 100 g of water at room temperature. Unfortunately, the enthalpy of solution values for the Group 1 chlorides as calculated above don't agree with the values given in the same Data Book: There should be no precipitates in Group 1, indicating that all Group 1 carbonates and sulphates are soluble. The sulphate of alkaline earth metals is less soluble. Also, the solubility increases as we move down the group. Carbonates of alkaline earth metals are insoluble in water. Solubility. Problems with the usual explanations. 1 litre of pure water will dissolve about 1 gram of calcium hydroxide at room temperature. The solubilities of these salts further increase on descending the group.Sulphates: Thermal stabilityThe sulphates of group-1 and group-2 metals are all thermally stable.solubility: sulphates of alkali metals are soluble in water. So sulphates and carbonates become less soluble as you go down the Group; hydroxides become more soluble. Sulphates of both group 1 and group 2 metals are stable towards heat. - Sodium sulphate 0.5 mol dm –3. Observations . Thermal stability. They are : 1.Heat of Hydration (Hydration Energy) and 2. Lattice Energy. The substances are listed in alphabetical order. Solubility of the sulphates. Contents Your answer would need to include: For sulphates: Solubility decreases as you go down the group. For Group 2, magnesium sulphate is soluble while strontium and barium sulphates are insoluble. By contrast, the least soluble Group 1 carbonate is lithium carbonate.
