Name the conditions on which osmotic pressure depends.

Explanation

**Step-by-Step Solution:**

1. **Definition of Osmotic Pressure**: Osmotic pressure is defined as the pressure required to stop the flow of solvent molecules from a dilute solution to a concentrated solution through a semipermeable membrane.

2. **Concentration of Solute**: The osmotic pressure is directly proportional to the concentration of solute in the solution. As the concentration of solute increases, the osmotic pressure also increases. This is because a higher concentration of solute means that there are more solute particles in the solution, which creates a greater tendency for solvent molecules to move into the solution.

3. **Electrolytic Nature of Solute**: The osmotic pressure also depends on the electrolytic properties of the solute. Electrolytes dissociate into ions in solution, and the number of particles (ions) affects the osmotic pressure. For example, a strong electrolyte that dissociates completely will produce more particles in solution than a weak electrolyte, leading to higher osmotic pressure.
