Semipermeable membrane. Name solution where net flow will occur?

A semipermeable membrane separates two aqueous solutions at 20 °C. For each of the following cases, name the solution into which a net flow of water (if any) will occur. Assume 100% dissociation for electrolytes.Solution A: 0.10M Al(NO3)3Solution B: 0.20M NaNO3 Solution A: 0.10M CaCl2Solution B: 0.50M CaCl2Solution A: 0.1M NaClSolution B: 0.1M KBrWhich group has a NET FLOW TOWARDS SOLUTION A, NET FLOW TOWARDS SOLUTION B, and NO NET FLOW. Please help!!

We had different numbers but the key is to multiply the Molarity by how many ions that are in each formula.For the first set: (0.10 M)(4) = 0.40 M && (0.20 M)(2) = 0.40 M so there will be no net flowFor the second set: Since their both CaCl2, it looks like the lower molarity will flow into the higher.For the third set: (0.10 M)(2) = 0.20 && (0.10 M)(2) = 0.20 .. KBr and NaCl both have 2 ions. There won’t be any net flow... Show More
