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, we need to analyze the water potential (Ψw) values given for chambers A and B.

### Step-by-Step Solution:

1. **Understand Water Potential (Ψw)**:
- Water potential (Ψw) is a measure of the potential energy of water in a system and is influenced by solute concentration. A higher (less negative) water potential indicates a lower concentration of solute, while a lower (more negative) water potential indicates a higher concentration of solute.

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

3. **Compare the Water Potential Values**:
- Between the two chambers, -1000 kPa (Chamber B) is less negative than -2000 kPa (Chamber A). This means that Chamber B has a higher water potential.

4. **Determine the Concentration of Solutions**:
- Since water potential is inversely related to solute concentration, the chamber with the higher water potential (Chamber B) must have a lower concentration of solute.
- Conversely, the chamber with the lower water potential (Chamber A) must have a higher concentration of solute.

5. **Conclusion**:
- Therefore, Chamber B, with Ψw = -1000 kPa, has the dilute solution, while Chamber A has the concentrated solution.

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