Solubility
Starter:
Match up the definition dominoes.

2. Definition Dominoes
Solubility The extent to which one substance dissolves in another
Solute The solid which dissolves in a solvent to form a solution
Soluble Able to dissolve in a given solvent
Solution A mixture of solute and solvent
Solvent A liquid in which another substance can be dissolved to make a solution
Saturated Solution A solution in which no more solute will dissolve

3. Solubility We are learning to:
Compare the solubility of solids and gases.
Plan and carry out an experiment.

4. Planning an Experiment
Design an experiment to find out if the amount of solute that can dissolve in water is affected by the temperature of the water.

5. Planning an Experiment
Variables
Temperature of water
Amount of water
Amount of solute
Independent – You will change…
Dependent – You will measure…
Fair test
Keep everything the same except the dependent and independent variables.

6. Planning an Experiment
Measuring
Count number of spatulas added until no more will dissolve.
Use the same amount of water, then weigh the solution before and after adding solute.

7. Planning an Experiment
Reliability
If someone else repeats the experiment will they get the same result?
How will you know you have got the correct result?
