Does sugar make water boil faster No. But salt can. ... The freezing point is also depressed in a solution of sugar and water (or salt and water, or any solution). This means one could use sugar to melt sidewalk ice in the winter. This is called freezing point depression. ... You're reading Does sugar make water boil faster...

Evaporation:is as the hot water cools, it loses mass to evaporation which forms water vapor. With less mass, the liquid has to lose heat to cool, and so it cools faster. The hot water freezes first but only because there is less water to freeze due to evaportion.

IF: (1) The number of moles of water and the number of moles of the three solutes added to the water is the same for each respective solution. AND ; (2) Each solution is cooled at the same rate. The answer would be that the sugar water would freeze faster.
