Question

If solution X has a 2% concentration of NaCl and solution Y has an 8% concentration of NaCl, which of the following statements is correct?

A. Solution X is hypotonic to solution Y.
B. Solution X has a higher osmotic pressure than solution Y.
C. Solution X has a lower concentration of water than solution Y.
D. Solution X is hypertonic to solution Y.
E. Solution X has a higher solute concentration than solution Y.

Answer 1

The correct option is A.

Step-by-step explanation:

Based on the information given in the question, solution X has 2% concentration of NaCl while solution Y has 8% concentration, this implies that solution X is hypotonic compare to solution Y.

A solution is said to be hypotonic when it contains a lower amount of solute and higher concentration of water when compared to another solution.

Thus, in comparison with Y solution, X solution is hypotonic, it has lower osmotic pressure, higher concentration of water (98%) and lower concentration of solute (2%).

Solution Y is hypertonic, has higher osmotic pressure, lower concentration of water (92%) and higher concentration of solute (8%).
