Calcium hydroxide solution is referred to as "lime water". I've been reading about it and it seems to have something to do with the reverse lattice enthalpy and the enthalpy of hydration. The sulphates become less soluble as you go down the group. Solubility figures for magnesium sulfate and calcium sulfate also vary depending on whether the salt is hydrated or not, but the variations are less dramatic. Silver acetate is sparingly soluble.

The symmetry is the same as that of methane. Can you explain what the changes in enthalpy are in each case? 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. With increase in the size of the central metal ion, the solubility of the sulphates of alkaline earth metals decreases as the hydration enthalpy from B e 2 + to B a 2 + decreases down the group. Strontium and barium sulphates are virtually insoluble in water. Doubtnut is better on App. Groups 1 and 2 metals could form (i) hydroxides and (ii) sulphates. This indicates that there are more hydroxide ions in solution than there were in the original water. alkali earth metals. The others are relatively rare. So the mass of sulfur must be calculated - this can be determined via analysing how much sulfur is contained in the Barium Sulfate precipitate. REASON: Both enthalpy change of lattice and enthalpy change of hydration are involved. (8) 5) Compare and contrast the chemistry of group 1 elements with that of group 2 on the basis of the following: a) Nature of oxides b) Solubility and thermal stability c) Polarizing power of cations d) Reactivity and reducing power 6) Groups 1 and 2 metals could form (i) hydroxides and (ii) sulphates.
