The solubility of the gas in liquids
The solubility of gases in liquids is an important concept in chemistry. It refers to the ability of a gas to dissolve in a liquid to form a homogeneous mixture. The solubility of a gas in a liquid is influenced by various factors, including temperature, pressure, and the nature of the gas and liquid.
- Henry’s Law: Henry’s Law describes the relationship between the pressure of a gas and its solubility in a liquid. According to Henry’s Law, the solubility of a gas is directly proportional to the partial pressure of the gas above the liquid. Mathematically, it can be represented as:C = k × PWhere C is the concentration of the dissolved gas in the liquid, P is the partial pressure of the gas, and k is the Henry’s Law constant for the specific gas-solvent system.
- Temperature: In general, the solubility of gases in liquids decreases with increasing temperature. This is because an increase in temperature provides more energy to the gas molecules, allowing them to escape from the liquid phase and form a gas phase. On the other hand, decreasing the temperature increases the solubility of gases in liquids.
- Pressure: The solubility of gases in liquids also depends on the pressure applied to the system. An increase in pressure typically increases the solubility of gases in liquids, following Henry’s Law. Higher pressure forces more gas molecules into the liquid phase, leading to higher solubility. Decreasing pressure has the opposite effect.
- Nature of the Gas and Liquid: The solubility of gases in liquids is influenced by the nature of both the gas and the liquid. Different gases have different solubilities in a particular solvent due to differences in their molecular properties. Similarly, the nature of the liquid, including its polarity, molecular structure, and intermolecular forces, affects the solubility of gases.
- Gas-Liquid Interaction: The interaction between the gas molecules and the liquid molecules also plays a role in determining the solubility. If the intermolecular forces between the gas and the liquid are strong, the solubility tends to be higher. For example, polar gases like ammonia (NH3) tend to have higher solubilities in polar solvents like water due to the formation of hydrogen bonds.
Understanding the solubility of gases in liquids is crucial in various fields, including environmental science, pharmaceuticals, and chemical engineering. It helps in designing processes for gas absorption, purification, and extraction from liquids, among other applications.
What is Required AIIMS-SYLLABUS Chemistry syllabus The solubility of the gas in liquids
The solubility of gases in liquids is a fundamental concept in chemistry. It refers to the ability of a gas to dissolve in a liquid to form a homogeneous mixture. While I don’t have access to the specific requirements of AIIMS-SYLLABUS, I can provide you with a general overview of the topic.
To understand the solubility of gases in liquids, the following aspects are typically covered:
- Henry’s Law: Henry’s Law describes the relationship between the pressure of a gas and its solubility in a liquid. It states that at a constant temperature, the solubility of a gas is directly proportional to its partial pressure. Mathematically, it can be expressed as C = k × P, where C is the concentration of the dissolved gas, P is the partial pressure of the gas, and k is the Henry’s Law constant.
- Factors affecting solubility: The solubility of gases in liquids is influenced by several factors:a. Temperature: Generally, the solubility of gases decreases with increasing temperature. This is because higher temperatures provide more energy to gas molecules, making them less likely to stay dissolved in the liquid.b. Pressure: Increasing the pressure usually enhances the solubility of gases in liquids. Higher pressures force more gas molecules into the liquid, leading to increased solubility.c. Nature of the gas and liquid: The solubility of a gas in a particular liquid depends on the nature of both the gas and the liquid. Different gases have different solubilities in a given solvent due to variations in molecular properties. Additionally, the polarity, molecular structure, and intermolecular forces of the liquid also play a role.
- Gas-Liquid interaction: The interaction between gas molecules and liquid molecules affects the solubility. If the intermolecular forces between the gas and liquid are strong, the solubility tends to be higher. For instance, polar gases like ammonia (NH3) have higher solubilities in polar solvents like water due to the formation of hydrogen bonds.
- Applications: Understanding the solubility of gases in liquids is essential in various fields, including environmental science, pharmaceuticals, and chemical engineering. It helps in processes like gas absorption, purification, and extraction from liquids.
Remember, the actual syllabus for AIIMS or any specific exam may differ. It’s important to refer to the official sources or exam authorities for the exact syllabus and depth of coverage for the solubility of gases in liquids.

The Solubility of Carbon Dioxide (CO2) in Water
Introduction: The solubility of gases in liquids is an important phenomenon in chemistry. In this case study, we will focus on the solubility of carbon dioxide (CO2) in water, which has significant implications in various fields such as environmental science, biochemistry, and chemical engineering.
Objective: To investigate the factors influencing the solubility of carbon dioxide in water and understand its applications in real-world scenarios.
Experimental Procedure:
- Temperature Variation: In a controlled laboratory setting, a series of experiments can be conducted to measure the solubility of CO2 in water at different temperatures. A carbon dioxide gas source is connected to a burette or gas delivery system, allowing controlled amounts of CO2 to be introduced into a fixed volume of water. The amount of dissolved CO2 can be determined by measuring the pressure change or using appropriate analytical techniques such as titration or gas chromatography.
- Pressure Variation: Similarly, experiments can be performed to study the effect of pressure on the solubility of CO2 in water. By altering the pressure of the carbon dioxide gas above the water sample while maintaining a constant temperature, the amount of dissolved CO2 can be measured. The pressure can be adjusted using a pressure regulator or gas syringe.
- Kinetics of Dissolution: The rate at which CO2 dissolves in water can be investigated by monitoring the change in concentration over time. This can be done by continuously measuring the concentration of dissolved CO2 using techniques like spectrophotometry or pH measurement.
- Effect of Salinity: The solubility of CO2 in water can be influenced by the presence of other dissolved substances, such as salts. Experiments can be conducted to observe the impact of varying salt concentrations on the solubility of CO2. Different salt solutions can be prepared, and the solubility of CO2 can be measured and compared to pure water.
Applications:
- Environmental Science: Understanding the solubility of CO2 in water is crucial for studying the carbon cycle, ocean acidification, and climate change. Increased levels of dissolved CO2 in the oceans can lead to acidification, affecting marine ecosystems and coral reefs.
