Stephen is given 500 ml of water at 32 ^oC. He continues to drop sugar cubes into the water while stirring until no more sugar cubes dissolve. The solution is said to be dilute saturated unsaturated supersaturated .

Stephen now filters this solution and carefully cools it to 22 ^oC. He then adds a single crystal of sugar. What is likely to happen? The crystal will dissolve. Nothing will happen to the crystal. Crystallisation will occur and the crystal will grow in size.

Peter continues to add sugar cubes to a container of water until no more can dissolve. Which one of the following actions will not cause more sugar to be dissolved? Add more water. Heat the water. Cool the water.

Which statement is true? When a salt crystal is placed in a saturated solution:

salt particles crystallise onto the crystal but no salt particle moves off the crystal into the solution. salt particles move from the crystal into the solvent. salt particles crystallise onto the crystal at the same rate as salt particles move off the crystal.

Jonathon drops a salt crystal into a glass containing a salt solution labelled unsaturated. What will likely happen to the salt crystal? nothing shrink and then grow. grow. dissolve.

Which one of the following actions will cause a solution to become supersaturated? Evaporate the solvent. Heat the solution. Add more solvent
