Therefore whatever little solubility these fluorides have that increase down the group. 7) 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 Downloads The periodic table - solubility of sulphates and carbonates of groups 1 and 2 - teacher BaSO4 is the least soluble. It goes on to look at my misgivings about these. An effective guide on solubility of Compounds of Group II Elements, including trends in the solubility of sulphates and trends in solubility of hydroxides. 1 Trends down the group; 2 Reactions with water and oxygen ; 3 Using Magnesium to extract Titanium; 4 Solubility of hydroxides and sulfates; 4 Solubility of hydroxides and sulfates . <> REASONS: there is a little change in the lattice enthalaphy BUT as the cation gets larger the hydration enthalaphy gets much smaller a large cation has a lower charge density and so is less attracted to water. Within group 2, the hydration energy decreases down the group while lattice energy is almost the same. to the extent of about 0.02 g per 100 g of water at room temperature. Although it describes the trends, there isn't any attempt to explain them on this page - for reasons discussed later. 1 answer.
