Answer:
Initially, compartment B, would have higher osmotic pressure than compartment A. As time goes, the solution would flows from compartment B to compartment A, increasing the level in that compartment A, up to the osmotic pressure is equal at each side of the membrane.
Step-by-step explanation:
- Initially both sides had the same level of water.
- While there is only distilled water, osmotic pressure is the same at each side of the membrane, and the system is at equilibrium.
- Osmotic pressure is a property related with the NaCl content in each side of the membrane.
- In order to occur a flow, a difference of pressure is mandatory, and the flow would be from the higher pressure source to the lower pressure sink.
- Then as initially there is a higher content of NaCl on compartment B, then this one would have the higher osmotic pressure.
- Then there would be a flow through the membrane in order to equilibrate pressure, that is why the level on compartment A would increase.
