The sulfate anion consists of a central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement. Group II elements have the outer shell configuration ns2. 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. solubility : Nitrates of group -1 and group-2 metals are all soluble in water. Since the atomic radii increase down the group it makes sense that the coordination numbers also increases because the larger the metal ion the more room there is for water molecules to coordinate to it. Physics. 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. However, all that information can be placed in a table as shown below, which makes it easier to locate solubility information for a particular ionic compound made up of a particular cation and a particular anion.

"Sulfate" is the spelling recommended by IUPAC, but "sulphate" was traditionally used in British English.. Calcium Oxide and Calcium carbonate can also be used to remove sulfur dioxide from flue gases. All sulfates possess an atomic structure based on discrete insular sulfate (SO 4 2-) tetrahedra, i.e., ions in which four oxygen atoms are symmetrically distributed at the corners of a tetrahedron with the sulfur atom in the centre. JIPMER 2014: The correct order of solubility of the sulphates of alkaline earth metals in water is Be > Mg > Ca > Sr > Ba. Sulphates: Thermal stability This trend can be explained by the decrease in the lattice energy of the hydroxide salt and by the increase in the coordination number of the metal ion as you go down the column.
