Solute potential of pure water and its solution are :

Options

A. 0 and 1
B. 0 and 0
C. 0 and more than 0
D. 0 and less than 0

Answer

To solve the question regarding the solute potential of pure water and its solutions, we can follow these steps:

### Step 1: Understand the Concept of Solute Potential
- **Definition**: Solute potential (Ψs) is a measure of the potential energy of water in a solution due to the presence of solute. It is influenced by the concentration of solute particles in the solution.

### Step 2: Determine the Solute Potential of Pure Water
- **Pure Water**: In pure water, there are no solute particles present. Therefore, the solute potential is zero.
- **Mathematical Representation**: Ψs (pure water) = 0

### Step 3: Determine the Solute Potential of a Solution
- **Solution**: When a solute is added to water, it lowers the water potential. The solute potential becomes negative because the presence of solute particles decreases the potential energy of the water.
- **General Rule**: The more concentrated the solution, the more negative the solute potential. For example, if a solution has a solute potential of -2 or -4, it indicates the presence of solute particles.
- **Mathematical Representation**: Ψs (solution) < 0 (negative value)

### Step 4: Conclusion
- **Final Answer**: The solute potential of pure water is 0, and the solute potential of a solution is less than 0 (negative).

### Summary of Results:
- Solute potential of pure water: **0**
- Solute potential of a solution: **less than 0 (negative)**
