Explaining the chemistry of Group 2 metals

When we consider the elements of Group 2 we are invariably only investigating magnesium, calcium, strontium and barium. All isotopes

Many ionic compounds are sparingly soluble – a good example is barium sulphate which has a solubility of 1.05 x

For a full understanding of why ionic compounds are soluble we need to consider both the enthalpy and entropy changes

Quick answer? It’s all about competing strengths of attraction between ions, between ions and water molecules, between water molecules themselves

We are all familiar with the classic picture of an ionic lattice – for example, for a compound such as
