The solubility of a gas in a liquid generally generally increases with

Options

A. (A) Increase in temperature
B. (B) Amount of liquid taken
C. (C) Decrease in temperature
D. (D) Reduction of gas pressure

Answer

To solve the question regarding the factors affecting the solubility of a gas in a liquid, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Solubility**:
- Solubility refers to the ability of a substance (in this case, a gas) to dissolve in a solvent (a liquid).

2. **Henry's Law**:
- The solubility of a gas in a liquid is governed by Henry's Law, which states that the solubility (S) of a gas is directly proportional to the pressure (P) of the gas above the liquid. This can be expressed mathematically as:
\[ S = k_H \cdot P \]
- Here, \( k_H \) is the Henry's Law constant.

3. **Effect of Pressure**:
- According to Henry's Law, if the pressure of the gas above the liquid increases, the solubility of the gas in the liquid also increases. This is because more gas molecules are forced into the liquid.

4. **Effect of Temperature**:
- The solubility of gases in liquids is also affected by temperature. Generally, as the temperature of the liquid increases, the solubility of the gas decreases. This is because higher temperatures provide gas molecules with more kinetic energy, causing them to escape from the liquid into the gas phase.

5. **Conclusion**:
- Therefore, the solubility of a gas in a liquid generally increases with an increase in pressure and a decrease in temperature.

6. **Final Answer**:
- The correct answer to the question is that the solubility of a gas in a liquid generally increases with **decrease in temperature**.
