Solutions

If there is more than the maximum amount of solute particles in a solution, it is said to be

• saturated

• unsaturated

• supersaturated

• concentrated

Oil does not dissolve when it is mixed with water. Oil is....

• insoluble in water

• saturated in water

• soluble in water

• all of the above

The saturation point of a sugar and water solution increases at higher temperatures. This is because...

• Sugar and water molecules move slower and their interactions make the sugar molecules stay together longer

• Sugar molecules move faster

• Water molecules spread out more, making more room for the sugar molecules. Water molecules speed up and collide with sugar molecules more frequently.

• Water molecules actually come apart into separate atoms and react with the sugar
