Solution a contains 10 millimolar of sodium chloride, solution b contains 10 millimolar of sodium chloride.
00:07
And the membrane separating them is permeable to chloride ion, but not sodium ion.
00:12
What is the charge of the potential difference that would be established across the membrane? so let's say this is a membrane in the middle, and then you have two solutions, a and b.
00:23
A has 100 millimolar of sodium chloride, and b has 10 millimolar sodium chloride.
00:38
So the two ions will completely dissociate.
00:42
So sodium on one side is 100 millimolar, and chloride is going to be 100mm.
00:51
Now, the other side, sodium is going to be 10mm, and chloride 10.
00:59
Millimeter.
01:01
So since chloride is i guess it's permeable, so the chloride actually will reach equilibrium after a while.
01:12
So you have a hundred on one side, ten on the other side.
01:17
So the chloride is going to move from a to b until it reach equilibrium.
01:23
So at equilibrium, chloride equals 100 millimolar, 10 millimolar divide by 2...
