Osmosis – movement of solvent molecules across a selectively-permeable membrane
– solvent molecules move from lower to higher solute concentration
A semipermeable membrane separates two aqueous solutions at 37 °C. For each of the following cases, name the solution into which a net flow of water (if any) will occur
The categories are: Net flow is toward solution A, Net flow is toward solution B, and no net flow
Place the following into the correct category above:
1) Solution A: 0.10 M NaCl (aq) AND solution B: 0.01 M NaCl (aq)
2) Solution A: 0.20 M KCl (aq) AND solution B: 0.20 M NaCl (aq)
3) Solution A: 0.10 M NaHCO3 (aq) AND solution B: 0.20 M NaHCO3 (aq)
