Solubility of the sulphates. Calcium hydroxide solution is referred to as "lime water". May solubility of sluphates can we use water, but if it is group 2 elements shows less solublity in nature compare to group 1 elements. The trend to lower solubility is, however, broken at the bottom of the group: barium carbonate is slightly more soluble than strontium sulfate. alkali earth metals. Sulphates become less soluble as you go down the group. Explore the properties of group 1 and 2 by examining whether precipitates form when you add drops of sulphate or carbonate solution to group 1 or 2 metal ions. Magnesium hydroxide appears to be insoluble in water. Thermal stability. 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. Trend in the solubility of sulphates. Let us begin by understanding the chemical bonding and molecular structure of sulfate. 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. These tetrahedral groups do not polymerize, and the sulfate group behaves as a single negatively charged molecule, or complex. The sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the −2 state. Sulphates of both group 1 and group 2 metals are stable towards heat.
