two solutions A&B are separated by a selectively permeable barrier. over a period of time the level of fluid on side A increases. which solution initially had the higher concentration of solute? explain your answer. Also State an example in your day-to-day living where you experience concentration gradient changes.

Solution

Answer is solution A had higher concentration of solute.

Please find below explanation and example.

This answer is based on the process of Osmosis i.e. \"Flow of solvent like water from lower concentration solution to a higher concentration solution through a semipermeable membrane\".

In the above scenario as the level of fluid on side A increases it means water was flowing on side A since it had a higher concentration of solutes. Whatever is more concentrated water will flow into it assuming there exist a selectively permeable membrane.

Day to day example: Pruning of the finger after keeping them in water for long period of time makes them wrinkly because in this case water is flowing from dilute to concentrated solution.
