Question

A contains 0.5M NaCl while Solution B contains 0.5M Sucrose. Solution A and Solution B are separated by a semi-permeable membrane. The membrane is permeable to water, NaCl, and Sucrose. Identify the direction of diffusion of water, NaCl, and Sucrose.

Answer 1

Answer:

Water and NaCl moves to the direction of sucrose

Explanation:

The semipermeable membrane Will allow NaCl since it ionizes and forms smaller individual ions, whereas the sucrose molecules doesn't ionize hence are the biggest molecules and would not pass through the membrane due to concentration gradient

Answer 2

Answer:

Direction of diffusion of water will be towards NaCl

Explanation:

The solution of NaCl is more osmotically active as compared to sucrose which is less osmotically active. So water will pass through the semi permeable membrane from the sucrose solution into the more concentrated and more osmotic NaCl solution by the process of osmosis.
