Comparing Solubility
These diagnostic questions and response activities (contained in the zip file) support students in being able to:
-
Recognise that stirring does not affect the solubility of a substance.
-
Recognise that increasing the volume of solvent does not increase the solubility of a substance.
-
Use data to predict observations of 100 cm3 of solution where the mass of solute is above, below or equal to the solubility.
-
Predict observable changes following the cooling of a saturated solution.
-
Link points on a solubility graph to macroscopic observations.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
Download the zip file for all the questions and activities.
