Lowest freezing point aqueous solution
WebFreezing point depression is a function of the amount of dissolved substance — but substance must be treated as distinct particles rather than compound. This is an important distinction because ionic compounds, when they dissolve in water, typically separate into hydrated anions and hydrated cations — two distinct species as far as freezing point … WebIf you were to create a 1m solution of each of the four compounds mentioned above, the freezing point depression and boiling point elevation for Na2SO4 and MgCl2 would be the same. Sodium chloride would be your second most effective, and glucose would be …
