Homework Statement
You have two solutions - Solution A = 0.5 M NaCl and 0.5 M KCl Solution B= 1.0 M NaCl
If Solution A and B are separated by
a) a membrane permeable to all three ions what will happen?
and
b) a membrane that ions can not pass through but that water can, what will happen?
Homework Equations
-------------------------------
The Attempt at a Solution
I'm pretty sure Part A is talking about passive transport/diffusion of two solutes. I know that 2 different solutions will end up traveling through the membrane until they reach equilibrium.
I'm also certain that Part B is talking about passive transport/osmosis, in which case the water would diffuse from the solution with less concentrated solution to the solution with more concentrated solution.
What I don't understand is how to use the moles of the given solutions to help me figure out what the right answer is. We had a question like this on a quiz that I got wrong and then also it is now on my homework, and he has yet to mention anything like this in class, so I don't know how to apply the knowledge of diffusion/osmosis to this question.
