Osmosis occurs when there is a different concentration of solute molecules on each side of the membrane. The drawing below shows a beaker containing a 30% salt solution. A plastic bag containing a 10% salt solution is hanging down into the solution in the beaker. What will happen to the bag after about 20 minutes?

nincompoop · Answer

what does that even mean? the word hypertonic does not explain what will happen

anonymous · Answer

My brain is just frozen right now

nincompoop · Answer

okay. let us unfreeze your brain by first defining what osmosis is.

anonymous · Answer

Ok I think the water will move from the bag into the 30 % salt solution

anonymous · Answer

ok

nincompoop · Answer

do you know diffusion?

anonymous · Answer

Used to know it... :(

nincompoop · Answer

do you want to check your notes or textbook?

anonymous · Answer

I guess it's like the process of molecules moving from an area of high to low concentration?

anonymous · Answer

ok will do so right now

nincompoop · Answer

good. now think of osmosis a kind of specialized diffusion, but the molecules involved this time is the water.

anonymous · Answer

It's not in my notebook, I believe my teacher gave us a sheet. I remember I was very knowledgeable on this but for some reason I have completely forgotten it, aybe I just need to refresh my memory

anonymous · Answer

Water molecules will move from area of high to an area of low concentration?

anonymous · Answer

so there is less water in thew bag so molecules will move from the bag into the 30% salt solution?
