Concentration flow

Members don't see this ad.

is conecentration flow important to know for the inorganic. I mean will there be a question if u have a 2 molar solution of nacl and a 1 molar solution of a nacl and they are separated by a semipermeable membrane where would the water flow, which way. Im having trouble understanding problems like this. If anyone can explain concentration flow it would be appreciated.

If you have a 2M solution of NaCl connected to a 1M NaCl, the 2M would have lower water [], and the 1M would have higher water [], so water would flow from the 1M NaCl to the 2M NaCl, probably until it has reached an equilibrium.

And if the nacl would be able to cross the membrane the nacl would go from the 2molar to the one molar????

Yes, the NaCl would from from high concentration to low concentration.
