Any substance that dissolves in water will lower its freezing point. This is called freezing point depression.

Here are some common examples:

* Salt (NaCl): This is why we use salt to melt ice on roads in the winter.

* Sugar (C12H22O11): This is why we add sugar to ice cream to lower its freezing point and make it softer.

* Ethanol (C2H5OH): This is why antifreeze is used in car radiators to prevent the coolant from freezing.

The more solute you add, the lower the freezing point will be. This is explained by the concept of colligative properties, which are properties of solutions that depend on the concentration of solute particles, not their identity.
