A solution has higher osmotic pressure than its standard solution. Which of the following term will be used for this solution?

Options

A. Isotonic
B. Hypertonic
C. Dilute
D. Hypotonic

Answer

To determine the term used for a solution that has a higher osmotic pressure than its standard solution, we can follow these steps:

### Step 1: Understand Osmotic Pressure
Osmotic pressure is the pressure required to prevent the flow of solvent into a solution via osmosis. It is a colligative property, meaning it depends on the number of solute particles in a solution rather than the identity of the solute.

### Step 2: Recall the Formula for Osmotic Pressure
The formula for osmotic pressure (π) is given by:
\[ \pi = i \cdot C \cdot R \cdot T \]
where:
- \( i \) = Van't Hoff factor (number of particles the solute dissociates into)
- \( C \) = concentration of the solution
- \( R \) = universal gas constant
- \( T \) = temperature in Kelvin

### Step 3: Analyze the Given Information
The question states that the solution has a higher osmotic pressure than its standard solution. This implies that the concentration of solute in this solution is greater than that in the standard solution.

### Step 4: Determine the Type of Solution
When a solution has a higher concentration than another solution (in this case, the standard solution), it is referred to as a **hypertonic solution**. In biological terms, a hypertonic solution has a higher osmotic pressure compared to the cytoplasm of a cell, causing water to move out of the cell, leading to cell shrinkage.

### Step 5: Conclusion
Based on the analysis, the solution with higher osmotic pressure than its standard solution is termed **hypertonic**.

### Final Answer
The term used for the solution is **hypertonic**.
