The correct Answer is:
To solve the question regarding the van't Hoff factor (i), we need to understand what it signifies in terms of solute behavior in a solution. ### Step-by-Step Solution: 1. **Understanding van't Hoff Factor (i)**: The van't Hoff factor (i) is defined as the ratio of the number of particles in solution after dissociation to the number of formula units of solute that were initially dissolved. 2. **Determining the Meaning of i > 1**: When the van't Hoff factor is greater than unity (i > 1), it indicates that the number of particles in solution is greater than the number of solute particles that were initially added. 3. **Interpreting the Implications**: This situation occurs when a solute dissociates into multiple particles. For example, if a solute like NaCl is dissolved, it dissociates into Na⁺ and Cl⁻ ions, effectively doubling the number of particles in solution. 4. **Conclusion**: Therefore, if the van't Hoff factor is greater than 1, it indicates that the solute has dissociated into more particles than it originally contributed. Hence, the correct answer to the question is that the solute in solution has dissociated. ### Final Answer: The van't Hoff factor more than unity indicates that the solute in solution has dissociated. ---
