Oxygen gas is collected at a pressure of 123 kpa – Oxygen gas, collected at a pressure of 123 kPa, plays a crucial role in various scientific and industrial applications. This article delves into the methods, equipment, and techniques involved in collecting oxygen gas at this specific pressure, exploring its significance and practical implications.

The collection of oxygen gas at 123 kPa requires specialized equipment and meticulous procedures to ensure safety and accuracy. This article provides a comprehensive overview of the processes involved, discussing the advantages and limitations of different methods, as well as the essential safety precautions that must be observed.

Pressure of Oxygen Gas

Oxygen gas, a vital component for life and industrial processes, exerts pressure due to the movement of its molecules. Pressure is a measure of the force exerted by gas molecules per unit area. In the context of oxygen gas, it becomes crucial to understand its pressure for safe handling and efficient utilization.

Pressure is typically measured in kilopascals (kPa), a metric unit representing the force of 1,000 newtons acting on an area of one square meter. The pressure of oxygen gas is commonly measured at 123 kPa, which is a standard reference point for many applications.

Methods for Collecting Oxygen Gas

Oxygen gas can be collected through various methods, each with its advantages and limitations:

• Cryogenic Distillation:Involves cooling air to extremely low temperatures, causing oxygen to condense and separate from other gases.
• Pressure Swing Adsorption (PSA):Utilizes a molecular sieve to selectively adsorb nitrogen, leaving behind pure oxygen.
• Electrolysis of Water:An electrochemical process that splits water molecules into hydrogen and oxygen.
• Thermal Decomposition of Metal Oxides:Heating certain metal oxides, such as potassium permanganate, releases oxygen gas.

The specific method used to collect oxygen gas at a pressure of 123 kPa is typically PSA or cryogenic distillation.

Equipment and Apparatus

Collecting oxygen gas at 123 kPa requires specific equipment and apparatus:

• Oxygen Generator:The device that produces oxygen gas, using methods like PSA or cryogenic distillation.
• Pressure Regulator:Controls and maintains the gas pressure at 123 kPa.
• Flow Meter:Measures the rate of oxygen flow.
• Pressure Gauge:Indicates the pressure of the oxygen gas.
• Gas Cylinder:Stores the collected oxygen gas at 123 kPa.

Safety precautions are paramount when handling oxygen gas, including proper ventilation, avoiding ignition sources, and using appropriate personal protective equipment.

Procedures and Techniques

Collecting oxygen gas at 123 kPa involves the following steps:

1. Ensure the oxygen generator is properly set up and calibrated.
2. Connect the generator to the pressure regulator and flow meter.
3. Set the pressure regulator to 123 kPa.
4. Open the gas cylinder valve and adjust the flow rate as needed.
5. Monitor the pressure gauge to maintain 123 kPa.
6. Collect the oxygen gas in the gas cylinder.

Potential sources of error include incorrect calibration of equipment, leaks in the system, and improper handling of the gas.

Applications and Uses, Oxygen gas is collected at a pressure of 123 kpa

Oxygen gas collected at 123 kPa has numerous applications:

• Medical:Oxygen therapy for respiratory ailments, anesthesia, and wound healing.
• Industrial:Metalworking, welding, and chemical processing.
• Aerospace:Life support systems and rocket propulsion.
• Environmental:Wastewater treatment and air purification.

Handling oxygen gas requires adherence to safety regulations, including proper storage, ventilation, and trained personnel.
