Answer:
Osmotic pressure
Explanations:
Colligative property is defined as the property of a solution that determines the ratio of solutes in solution to the total particles of the solvent. They are linked to solution's concentration such as its molarity, molality and normality. Examples of colligative property include;
• Freezing point depression
,
• Lowering of vapour pressure
,
• Osmotic pressure
,
• Boiling point elevation.
Based on the explanations above, we can conclude that Osmotic pressure is a colligative property
