In reverse osmosis the solvent molecules flow from …………to solvent side.

Answer

**Step-by-Step Solution:**

1. **Understanding Reverse Osmosis**: Reverse osmosis is a process where solvent molecules move through a semipermeable membrane from a region of higher solute concentration (solution side) to a region of lower solute concentration (solvent side) when pressure is applied.

2. **Pressure Application**: In reverse osmosis, pressure is applied to the solution side. This pressure must be greater than the osmotic pressure of the solution to reverse the natural osmotic flow.

3. **Direction of Flow**: Normally, in osmosis, solvent molecules flow from the solvent side (where there is a lower concentration of solute) to the solution side (where there is a higher concentration of solute). However, in reverse osmosis, due to the applied pressure, the flow is reversed.

4. **Final Answer**: Therefore, in reverse osmosis, the solvent molecules flow from the solution side to the solvent side.

**Final Answer**: The solvent molecules flow from the solution side to the solvent side.
