Group 2 metal compound reactions - AS Chemistry
This is an AS Chemistry lesson on the group 2 metal compounds and their reactivity and solubility at grades C to A. For grade C students write symbol equations. Note that the hydroxides and sulphates show opposite trends in solubility. For grade B they consider the aluminium sulphate Camelford water poisoning in Cornwall and write ionic equations. Note that all ions are aqueous and that Barium chloride and aluminium sulphate are soluble compounds. For grade A they analyse different data and use this to explain trends in solubility of group 2 compounds. For an engaging starter you could show the reaction of potassium with water and ask students to predict how the reactivity of group 2 metals would be different (less owing to increased charge density and 2 ionisation energies to make the ion).
