Concentration gradients occur when the amount of materials in two different areas are not equal. ...O
A
B
Area A in this diagram has a high concentration of water.
Area B above has a low concentration of water
Area A above has a low concentration of solute (dissolved particles).
Area B above has a high concentration of solute.
Materials will naturally move from an area of high concentration to an area of low concentration. This occurs
without any outside energy being required. Materials will move from one area to another until the
concentrations in all areas are basically equal.
Assuming that no outside energy is supplied to the above system, which of the statement(s) below are false?
1. Over time, more water will move away from area A than will move into area A.
2. As time progresses, more solute will move into area B than will move out of area B.
3. The same amount of water will move out of both areas A and B as time progresses.
4. The amount of solute in area A will increase over time.
5. The amount of water in are B will decrease as time passes.
6. Solute will move into and out of area B at the same rate.
7. Equal amounts of solute will move from both areas into the other area.
8. After a certain period of time, the concentrations of water and solute in both areas will become equal.
