In the process of osmosis, volume of solvent

Options

A. Decrease
B. Increase
C. Remian constant
D. Volume has no relation to osmosis

Answer

**Step-by-Step Solution:**

1. **Understanding Osmosis**: Osmosis is the movement of water (solvent) across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process aims to equalize solute concentrations on both sides of the membrane.

2. **Volume of Solvent**: When considering the volume of the solvent (water) involved in osmosis, it is important to note that the total volume of solvent in the system (inside and outside the cell) remains constant. This is because osmosis involves the movement of water molecules, but does not add or remove water from the system.

3. **Osmotic Pressure**: Osmotic pressure is the pressure required to stop the flow of water across the membrane. It is inversely proportional to the volume of solvent. This means that as the volume of solvent increases, the osmotic pressure decreases, and vice versa.

4. **Before and After Osmosis**: Before osmosis occurs, the volumes of solvent inside and outside the cell are measured. After osmosis has taken place, while the distribution of water may change (moving from one side of the membrane to the other), the total volume of solvent in the system remains the same.

5. **Conclusion**: Therefore, in the process of osmosis, the volume of the solvent remains constant. The correct answer to the question is "remain constant".

**Final Answer**: In the process of osmosis, the volume of solvent remains constant.
