Which of the following would exert maximum osmotic pressure?

Options

A. Decimolar aluminium sulphate
B. Decimolar barium chloride
C. Decimolar sodium chloride
D. A solution obtained by mixing equal volumes of (B) and (C) and filtering

Explanation

To determine which solution would exert maximum osmotic pressure, we need to analyze the dissociation of each solute in the given options and calculate the total number of particles produced from each solute. Osmotic pressure is a colligative property that depends on the number of solute particles in a solution.

### Step-by-Step Solution:

1. **Understanding Osmotic Pressure**:
- Osmotic pressure (π) is directly proportional to the number of solute particles in a solution. The formula for osmotic pressure is given by:
\[
\pi = iCRT
