Osmosis is the net flow of solvent molecules through a semipermeable membrane from a solution of lower concentration to a solution of higher concentration.

In reverse osmosis, the solvent molecules are flow from a solution of higher concentration to a solution of lower concentration.

1. 4.2 M HNO3 to 2.4 M HNO3 :

In this, the solvent molecules flow from 4.2 M solution (higher concentration) to 2.4 M solution (lower concentration).

Hence, the process is a reverse osmosis.

---------------------------------------------------------------------------------------------------------------------------------

2. 0.4 M NaCl to 0.8 M NaCl :

In this, the solvent molecules flow from 0.4 M solution (lower concentration) to 0.8 M solution (higher concentration).

Hence, the process is an osmosis.

-----------------------------------------------------------------------------------------------------------------------------------

3. 1 M KOH to 2 M KOH :

In this, the solvent molecules flow from 1 M solution (lower concentration) to 2 M solution (higher concentration).

Hence, the process is an osmosis.

--------------------------------------------------------------------------------------------------------------------------------------

4. 0.6 M KCl to 0.3 M KCl :

In this, the solvent molecules flow from 0.6 M solution (higher concentration) to 0.3 M solution (lower concentration).

Hence, the process is a reverse osmosis.

------------------------------------------------------------------------------------------------------------------------------------------

5. 1 M CH3COOH to 0.4 M CH3COOH :

In this, the solvent molecules flow from 1 M solution (higher concentration) to 0.4 M solution (lower concentration).

Hence, the process is a reverse osmosis.

------------------------------------------------------------------------------------------------------------------------------------------

6. 0.01 M Sucrose to 1 M Sucrose

In this, the solvent molecules flow from 0.01 M solution (lower concentration) to 1 M solution (higher concentration).

Hence, the process is an osmosis.
