Final answer:
Osmotic pressure is a colligative property of solutions observed using a semipermeable membrane. It is the pressure difference between two sides of a semipermeable membrane that separates a pure solvent from a solution. Osmotic pressure is a result of the tendency of solvent molecules to move from a lower concentration solution to a higher concentration solution through osmosis.
Step-by-step explanation:
Osmotic pressure is a colligative property of solutions that is observed using a semipermeable membrane. It is the pressure difference between the two sides of a semipermeable membrane that separates a pure solvent from a solution prepared from the same solvent. Osmotic pressure is a result of the tendency of solvent molecules to move from a lower concentration solution to a higher concentration solution through osmosis.
