Question

The following pairs of aqueous solutions are separated by a semipermeable membrane. In which direction will the solvent flow?a. A = 3.45 M calcium iodide; B = 3.45 M sodium bromideb. A = 5.00 M sucrose; B = 3.00 M potassium nitrate

Answer 1

osmosis is a process where by solvent or fluid molecules flow from low concentration to high concentration.

So in

A.solvent will flow from B to A because

B = 3.45 M sodium bromide is more concentrated than 3.45 M calcium iodide;

b) solvent still flow from B to A because

A = 5.00 M sucrose is less concentrated than B = 3.00 M potassium nitrate
