1. TODAY, let’s find out… WHAT happens in our body to our cells when we drink too much salt??

2. date Diffusion: when a solution spreads out everywhere. This happens by itself because particles can naturally move around (vibration, rotation, translation of atoms) Trying to make EQUAL CONCENTRATION.

4. What is diffusing? a)The solute a)The solvent

5. date What is diffusing? a)The solute a)The solvent

6. date What is diffusing? a)The solute a)The solvent

7. date What is diffusing? a)The solute a)The solvent

8. date What is diffusing? a)The solute a)The solvent

9. date What is diffusing? a)The solute a)The solvent

10. date Up until now, we only looked at cases where the solute diffuses. What is diffusing? a)The solute a)The solvent

11. date Up until now, we only looked at cases where the solute diffuses. What is diffusing? a)The solute a)The solvent The are cases where a LIQUID SOLVENT is the one diffusing!!!

12. date Up until now, we only looked at cases where the solute diffuses. What is diffusing? a)The solute a)The solvent The are cases where a LIQUID SOLVENT is the one diffusing!!! =we call this OSMOSIS!

13. date Up until now, we only looked at cases where the solute diffuses. What is diffusing? a)The solute a)The solvent The are cases where a LIQUID SOLVENT is the one diffusing!!! =we call this OSMOSIS! We will learn about osmosis of the solvent WATER.

14. date

15. Osmosis: is the diffusion of a LIQUID SOLVENT, going through a semipermeable membrane. We will learn about WATER only in this class.

16. date Osmosis: is the diffusion of a LIQUID SOLVENT, going through a semipermeable membrane. We will learn about WATER only in this class.

17. date Membrane:

18. date Membrane: wall, barrier. Stops things from passing through.

19. date Membrane: wall, barrier. Stops things from passing through. Permeable membrane:

20. date Membrane: wall, barrier. Stops things from passing through. Permeable membrane: wall that allows liquids to pass through.

21. date Membrane: wall, barrier. Stops things from passing through. Permeable membrane: wall that allows liquids to pass through. Semipermeable membrane:

22. date Membrane: wall, barrier. Stops things from passing through. Permeable membrane: wall that allows liquids to pass through. Semipermeable membrane: wall that allows ONLY CERTAIN liquids to pass through.

23. date Membrane: wall, barrier. Stops things from passing through. Permeable membrane: wall that allows liquids to pass through. Semipermeable membrane: wall that allows ONLY CERTAIN liquids to pass through. In osmosis of water, only water can pass through!

24. date Osmosis: is the diffusion of a LIQUID SOLVENT. Going through a semipermeable membrane.

25. date Osmosis: is the diffusion of a LIQUID SOLVENT. Going through a semipermeable membrane.

26. date Osmosis: is the diffusion of a LIQUID SOLVENT. Going through a semipermeable membrane. 728

27. date Osmosis: is the diffusion of a LIQUID SOLVENT. Going through a semipermeable membrane. 7287

28. date 728 The whole point of diffusion or osmosis is to have EQUAL CONCENTRATION!!
