Question

What is the value of the Van't Hoff factor (i) for solutes that dissociate in water?

• A. \( > 1 \)
• B. \( < 1 \)
• C. \( = 0 \)
• D. Not defined

Hint:

The Van't Hoff factor \( i \) is greater than 1 for solutes that dissociate into more than one particle in solution.

Answer 1

The Correct Option is A

Step 1: Understand the Van't Hoff factor.
The Van't Hoff factor \( i \) represents the number of particles into which a solute dissociates in solution.
For solutes that dissociate in water, such as salts, \( i \) is greater than 1 because the solute dissociates into multiple ions.
Step 2: Identify the correct option.
For dissociating solutes (like NaCl), \( i \) will be greater than 1, as each formula unit dissociates into two or more ions.
