Concentration
With this simulation, students build an understanding of solution concentration by varying amounts of solute, solvent, and solution. Experimenting with several different chemicals in solid and concentrated solution form, students can develop qualitative and quantitative relationships.
Learning objectives include:
*Describe the relationships between volume and amount of solute to solution concentration.
*Explain how solution colour and concentration are related.
*Predict how solution concentration will change for any action (or combination of actions) that adds or removes water, solute, or solution, and explain why.
*Design a procedure for creating a solution of a given concentration.
*Design and justify a procedure for changing a solution from one concentration to another.
*Identify when a solution is saturated and predict how concentration will change for any action or combination of actions where water or solute change.
