Which is most concentrated at 80 degrees Celcius?

Question

a) a saturated solution of NaNO3 in water

b) a saturated solution of LiCl in water

c) a saturated solution of KCl in water

d) All saturated solutions have the same concentration

Sugar in water.....

a) glues water molecules together, and so makes water freeze at a temperature greater than 0 degrees celcius

b) gets in the way of water molecules coming togerher and so makes water freeze at temperatures lower than 0 degrees celcius

c) has no effect on the freezing point o water, because sugar does not dissovle in water

d) has no effect on the freezing point of water, because water is nonpolar

Answer 1

Sugar in water would decrease its freezing point because of its colligative properties. An addition of solute would cause a freezing point depression.
