Properties of Solutions
The glacier on the shore is frozen solid, yet the ocean remains liquid. What makes the difference?
The salt present in ocean water is the key factor.
Here, salt is the solute, and water is the solvent. When a solute is added to a solvent, it can change the solvent’s properties, including its freezing and boiling points.
Take water, for example. Pure water freezes at 0°C, but adding salt lowers its freezing point.
This happens because salt particles interfere with water molecules, making it harder for them to bond and form ice.
Have you ever seen trucks spreading salt on icy roads? The salt dissolves into the ice, lowering its freezing point and causing it to melt, which keeps roads safer.
In addition, water normally boils at 100°C, but adding a solute like salt raises its boiling point slightly.
This happens because solute particles make it harder for water molecules to turn into steam.
That’s why adding salt to water raises its boiling point slightly, allowing food to cook at a slightly higher temperature.
