"Osmosis is flow of solution from higher concentration to solution of lower concentration through semi-permeable membrane" What is incorrect in the statements ?

Options

A. Exact concentration of sulution is not given
B. Character of semipermeable membrane is not given
C. Flow of solution is not possible through semipermeable membrane
D. All the above

Answer

To analyze the statement "Osmosis is flow of solution from higher concentration to solution of lower concentration through semi-permeable membrane," we need to identify what is incorrect about it. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Definition of Osmosis
Osmosis is specifically defined as the movement of solvent molecules (usually water) from a region of higher solvent concentration (or lower solute concentration) to a region of lower solvent concentration (or higher solute concentration) through a semi-permeable membrane.

**Hint:** Remember that osmosis involves the movement of solvent, not the solution itself.

### Step 2: Identify the Incorrect Part of the Statement
The statement incorrectly describes osmosis as the flow of the solution from higher concentration to lower concentration. In reality, osmosis refers to the movement of solvent molecules, not the entire solution.

**Hint:** Focus on the key terms: "solution" vs. "solvent."

### Step 3: Clarify the Role of the Semi-Permeable Membrane
A semi-permeable membrane allows only certain molecules (typically solvent molecules) to pass through, while restricting the passage of solute molecules. This is crucial in the process of osmosis.

**Hint:** Think about what a semi-permeable membrane does—does it allow solute or solvent to pass?

### Step 4: Conclusion
The incorrect part of the statement is that it refers to the "flow of solution" instead of the "flow of solvent." Therefore, the correct interpretation of osmosis should focus on the movement of solvent molecules, not the entire solution.

**Hint:** Revisit the definition of osmosis to reinforce the correct concept.

### Final Answer
The incorrect part of the statement is that it suggests the flow of solution occurs, whereas osmosis specifically involves the movement of solvent molecules through a semi-permeable membrane.
