If in an osmotic system, one chamber (A) has `Psi_(w)-2000 KP_(a)` while the other (B) has -1000 `KP_(a)`, which chamber has dilute solution ?

Options

A. Chamber A
B. Chamber B.
C. Both chambers have equal concentration.
D. Data insufficient

Answer

To determine which chamber has a dilute solution based on the given water potentials, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Water Potential (Ψw)**:
Water potential (Ψw) is a measure of the potential energy of water in a system. It indicates how much water can move freely. The more negative the water potential, the less free energy water has, which typically correlates with a higher concentration of solutes.

2. **Identify the Water Potentials**:
- Chamber A has Ψw = -2000 kPa
- Chamber B has Ψw = -1000 kPa

3. **Compare the Water Potentials**:
The water potential in Chamber A (-2000 kPa) is more negative than in Chamber B (-1000 kPa). This indicates that Chamber A has a higher concentration of solutes compared to Chamber B.

4. **Determine the Concentration of Solutions**:
In general, a solution with a higher concentration of solutes will have a more negative water potential. Therefore, since Chamber A has a more negative water potential, it indicates that Chamber A is more concentrated.

5. **Conclusion**:
Since Chamber B has a less negative water potential (-1000 kPa), it indicates that Chamber B has a lower concentration of solutes and is therefore the dilute solution.

### Final Answer:
Chamber B has the dilute solution.
