Solubility of `CO_(2)` is ________ times higher than that
of `O_(2)`

Options

A. 40 - 45
B. 20 - 25
C. 100 - 200
D. 200 - 300

Answer

To solve the question regarding the solubility of carbon dioxide (CO₂) compared to that of oxygen (O₂), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Solubility**:
- Solubility refers to the ability of a substance to dissolve in a solvent, in this case, how well CO₂ and O₂ can dissolve in water.

2. **Research Solubility Values**:
- It is known from biological studies that the solubility of CO₂ in water is significantly higher than that of O₂.

3. **Identify the Ratio of Solubility**:
- Based on scientific data, the solubility of CO₂ is approximately 20 to 25 times higher than that of O₂. This is due to the chemical properties of CO₂, which allow it to form carbonic acid when it reacts with water.

4. **Select the Correct Answer**:
- Given the options (40 to 45, 20 to 25, 100 to 200, 200 to 300), the correct answer is **20 to 25**.

### Final Answer:
The solubility of CO₂ is **20 to 25 times** higher than that of O₂.
