Four alternatives are given in each part of this question. Select the correct alternative and write it in your answer-book:
Which of the following has lowest osmotic pressure?
Show Hint
Osmotic pressure follows the relation \( \pi = iMRT \), where \( i \) is the van't Hoff factor, representing the number of particles a solute dissociates into.

The Correct Option is B
Solution and Explanation
Step 1: Osmotic pressure is directly proportional to the number of dissolved particles in a solution.
Electrolytes dissociate into multiple ions, increasing the number of solute particles in solution.
Gold solution is a colloidal solution and has the lowest osmotic pressure as it contains fewer dissolved ions compared to ionic compounds like potassium chloride or magnesium chloride.
