I know that osmosis occurs faster in fresh water...something to do with density/salinity factor I think. Can you explain in a clear manner? Thanks, RB ahh that'll do but to put it as simply as possible, fresh water is lighter and thinner than salt so it gets in easier. Thinner? You have some viscosity data to back this up? More likely fresh water exhibits a higher osmotic pressure because the difference in water concentration is greater in fresh than brine. (osmotic pressure being proportional to the differences in concentration on either side of the membrane) Very close, but the osmotic pressure of fresh water is low.
