Osmosis is the movement of water against the concentration of A and along the concentration of B. A and B are

Options

A. Solvent, Solvent
B. Solute, Solute
C. Solvent, Solute
D. Solute, Solvent

Answer

**Step-by-Step Text Solution:**

1. **Understanding Osmosis**: Osmosis is defined as the movement of water (or solvent) through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

2. **Identifying the Components**: In the question, we have two components: A and B. We need to determine what these represent in the context of osmosis.

3. **Movement of Water**: The question states that osmosis involves the movement of water against the concentration of A and along the concentration of B. This implies that:
- Water moves from an area of lower concentration of solute (higher concentration of water) to an area of higher concentration of solute (lower concentration of water).

4. **Defining A and B**:
- Since water is moving against the concentration of A, A must represent the solute (the substance dissolved in water).
- Conversely, since water is moving along the concentration of B, B must represent the solvent (which is water in this case).

5. **Conclusion**: Therefore, we can conclude:
- A = Solute
- B = Solvent

**Final Answer**: A is the solute and B is the solvent.
