Dissolution of ionic compounds generally involves an increase in entropy (+ΔS°), but for a few specific metal ions, dissolution of the ionic compound can lead to a decrease in entropy. For example, the dissolution of magnesium chloride (MgCl2) has a ΔS° = -115 J K-1 mol-1. Explain this decrease in entropy.
