Question

In a system with a semipermeable membrane, why does the side with higher mobility ions become more positively charged?

Accepted Answer

Because ions with higher mobility move faster, leaving behind slower-moving ions, creating a charge imbalance.

Answer

Because ions with higher mobility do not move at all.

Answer

Because ions with higher mobility are negatively charged and accumulate on one side.

Answer

Because ions with higher mobility are repelled by the membrane.
