Presentation Transcript

1. What is a solution? What happens when we dissolve something? * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

2. Investigation Weigh the beaker you have been given Put 100ml of water into the beaker and weigh it again Weigh the salt you have been given Dissolve the salt Weigh the solution you have made What have you found out? * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

3. Does it dissolve? calcium carbonate copper sulphate sugar salt graphite copper oxide Is soluble Is not soluble * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

4. What is happening? The solution Peas (these are the salt molcules) Rice (this is the water) salt water molecules mixed up spread out same mass * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

5. * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

6. solvent (excess) solute solution * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

7. How many spoons dissolved Temperature oC * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

8. Solubility experiment Fill a beaker of water to 100ml Take the temperature of the water Count how many flat spoons of salt will dissolve in that beaker Write your results down What did we find out? What can you say about solubility and the temperature of the water? * ** *** Use the key words dissolved and solution correctly to describe this experiment L3 * ** *** Describe how temperature affects solubility L4 Explain what a saturated solution is L5 Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

9. * ** *** Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving

10. * ** *** Use the key words dissolved and solution correctly to describe this experiment * ** *** Describe how temperature affects solubility Explain what a saturated solution is Identify the solvent, solute and solution Describe a solution with key words Use the particle model to explain dissolving
