Question

The following set of solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations. The pressure of the system is then manipulated such that movement is from the solution listed first to the solution listed second.Classify each set of solutions based on the movement of solvent from the first solution listed to the second solution listed as osmosis or reverse osmosis. 1. 4.2 M HNO3 to 2.4 M HNO3 2. 0.4 M NaCl to 0.8 M NaCl 3. 1 M KOH to 2 M KOH 4. 0.6 M KCl to 0.3 M KCl 5. 1 M CH3COOH to 0.4 M CH3COOH 6. 0.01 M Sucrose to 1 M Sucrose

Answer 1

Answer:

1. Reverse osmosis

2. Osmosis

3. Osmosis

4. Reverse osmosis

5. Reverse osmosis

6. Osmosis

Explanation:

The osmosis is the process when the solvent goes through a membrane from a side with a low concentration of solute to a higher concentration, to achieve an equilibrium. When the movement is doing on the opposite side (from higher concentration to low), the process is called reverse osmosis.

1. It is going from a higher to a low concentration, so it's reverse osmosis.

2. It's going from a low to a higher concentration, so it's osmosis.

3. It's going from a low to a higher concentration, so it's osmosis.

4. It is going from a higher to a low concentration, so it's reverse osmosis.

5. It is going from a higher to a low concentration, so it's reverse osmosis.

6. It's going from a low to a higher concentration, so it's osmosis.
