New insights into the role of solution additive anions in Mg2+ dehydration: implications for mineral carbonation

Computer simulations of the Mg2+ dehydration mechanism show that solution additives can stabilise undercoordinated Mg2+ hydration configurations, opening up coordination sites on the central Mg2+ ion, promoting Mg-carbonates nucleation and growth.
