Question

2. Predict what might happen in the following situation, in which you assume that the membrane is permeable to water and to very small uncharged molecules (in this case, oxygen). Write down what you think might happen in terms of net diffusion of both water and oxygen. 0.15M NaCl 0.15 M NaC 1.5 M O2

Answer 1

Since concentration of oxygen is higher outside the membrane, the oxygen molecules would move inside until they reach equillibrium.

while the water molecules are in equal concentration both inside as well as outside the membrane so they should remain where they are without any net movement. Same can be sait for NaCl as their concentration is also same for inside and outside of membrane.
