Question

The diagram below shows two solutions that are separated by a semi-permeable membrane. In which direction will most water molecules move?

• A. From X to Y, decreasing the concentration gradient of sucrose
• B. From X to Y, increasing the concentration gradient of sucrose
• C. From Y to X, decreasing the concentration gradient of sucrose
• D. From Y to X, increasing the concentration gradient of sucrose

Answer 1

The correct option is A From X to Y, decreasing the concentration gradient of sucrose

Most water molecular move from x to y decreasing the concentration gradient of sucrose. The solution will always move down the concentration gradient.

This means the water always move from this is more water to where there is less water.

Therefore, water will move from a hypotonic solution to the hypertonic solution.
