WebThis is consistent with the freezing point depression formula, as Mg has less mass than Ca. Beyond 24%, CaCl2 is superior. This is because the eutectic point of MgCl2-water is at 21.6 percent, whereas the eutectic point of CaCl2-water is at 30%. The freezing point depression formula is only valid at reasonably low concentrations.
