Question

question 10
an isotonic solution is a solution that has the:
a less solute particles than body fluids
b same solute (solid) concentration as body fluids
c none of these
d more solute particles than body fluids

Explanation:

An isotonic solution is defined as a solution that has the same solute concentration as body fluids. This means there is no net movement of water across a semi - permeable membrane (such as a cell membrane) when the solution is compared to body fluids.

• Option A: A solution with less solute particles than body fluids is a hypotonic solution.
• Option B: This is the correct definition of an isotonic solution.
• Option C: Since Option B is correct, this is incorrect.
• Option D: A solution with more solute particles than body fluids is a hypertonic solution.

Answer:

B. same solute (solid) concentration as body fluids
