If `0.1 M` solution of glucose and `0.1 M` solution of urea are placed on two sides of the semipermeable membrane to equal heights, then it will be be correct to say that

Options

A. water will flow from urea solution to glucose
B. urea will flow toward glucose solution
C. glucose will flow toward urea solution
D. there will be no net movement

Explanation

To solve the problem, we need to analyze the situation involving two solutions separated by a semipermeable membrane. Here’s a step-by-step breakdown of the reasoning:

### Step 1: Understand the Solutions
We have two solutions:
- A `0.1 M` solution of glucose
- A `0.1 M` solution of urea

Both solutions are at equal heights on either side of a semipermeable membrane.

**Hint:** Remember that molarity (M) indicates the concentration of solute in a solution.

### Step 2: Identify the Nature of the Membrane
The membrane is semipermeable, meaning it allows the passage of solvent molecules (water) but not solute molecules (glucose or urea).

**Hint:** Focus on what can pass through the membrane. Only the solvent can move, not the solutes.

### Step 3: Determine the Osmotic Pressure
Osmotic pressure is determined by the concentration of solute particles in the solution. Since both solutions have the same molarity (`0.1 M`), they exert the same osmotic pressure.

**Hint:** Compare the concentrations of the two solutions. If they are equal, the osmotic pressures will also be equal.

### Step 4: Analyze the Direction of Water Movement
In osmosis, water moves from an area of lower solute concentration to an area of higher solute concentration. However, since both solutions are `0.1 M`, they are isotonic, meaning there is no concentration gradient.

**Hint:** Recall that osmosis occurs when there is a difference in solute concentration. Here, both sides are equal.

### Step 5: Conclusion
Since both solutions have the same concentration, there will be no net movement of water across the semipermeable membrane. The system is in equilibrium.

**Final Answer:** There will be no net movement of water between the two solutions.

### Summary of the Steps:
1. Identify the solutions and their concentrations.
2. Recognize the properties of the semipermeable membrane.
3. Determine the osmotic pressure based on solute concentration.
4. Analyze the direction of water movement based on osmotic principles.
5. Conclude that there is no net movement due to equal concentrations.
