Question

If two solutions of 5% glucose and 10% glucose are kept in a trough separated by a
semipermeable membrane, what will you observe after one hour?

Answer 1

Due to osmosis the solutions will get mixed up with each other

Answer 2

Answer:

After 1 hour, the volume of 10% glucose solution will increase and volume of 5% glucose solution will decrease.

Explanation:

Solution of 5% glucose is hypotonic compared to solution of 10% glucose. Since the membrane separation them is semi-permeable, water from the hypotonic solution (or 5% glucose solution) will move to the hypertonic solution(or 10% glucose solution). Hence, after 1 hour, the volume of 10% glucose solution will increase and volume of 5% glucose solution will decrease.
