In comparing two solutions, which has the greater solute concentration?

• A. Isotonic
• B. Osmosis
• C. Hypertonic
• D. Hypotonic

Answer: (C)

Tonicity describes how solute-rich a solution is relative to another. The solution with more dissolved particles per unit volume is hypertonic relative to the other. Isotonic means equal solute concentration on both sides, and hypotonic means lower solute concentration than the other. Osmosis is the movement of water toward the side with higher solute concentration, driven by that gradient. So, the solution with the greater solute concentration is the hypertonic one.
