- Osmosis Definitions
- Concentrated Solution
- solution containing large amount of solute
- Opposite of dilute
- Solute Concentration
- Amount of solute dissolved in a solvent in a solution
- High solute concentration means low water potential
- Dilute Solution
- Solution containing small amount of solute, compared to solvent
- Solvent: Greatest part of the solution in which the solute is dissolved in.
- Solute: Substance dissolved in the solution.
- Opposite of concentrated
- Solution containing small amount of solute, compared to solvent
- Water Potential
- Pure water has a water potential of 0, anything not pure is a negative number
- represented by
- The tendency of water to move from one area to another.
- A low water potential has more solute molecules and less water molecules.
- A high water potential has more water molecules and less solute molecules.
- Water Concentration
- The amount of ingredients or parts in relation to the other ingredients or parts.
- E.g. salt in salt water
- Hypotonic
- Water potential outside the cell is higher than inside so water moves out
- Hypertonic
- Water potential outside the cell is lower than inside so water moves out of the cell
- Concentrated Solution
- Amount of solute dissolved in a solvent in a solution
