Anomalous x-ray diffraction studies of Sr2+ hydration in aqueous solution

An overview is given of anomalous x-ray diffraction (AXD) results on the hydration of Sr2+ in a concentrated solution of strontium chloride. Results from AXD on the hydration of the Sr2+ ion are compared with those obtained from previous techniques. These results are also compared in conjunction with results for Mg2+ and Ca2+ in order to discern any trends in the hydration properties of the alkaline earth series
