GAS JAR Meaning and
Definition
-
A gas jar, also known as a bell jar or pneumatic trough, is a laboratory apparatus used to collect and preserve gases. It typically consists of a cylindrical glass or plastic container with a wide mouth and a tight-fitting lid. The jar may have a stopcock or valve at the bottom to control the flow of gas.
Gas jars are primarily used to collect gases that are produced during chemical reactions or obtained from a gas supply. They provide a controlled environment for the gases, preventing their escape into the surrounding atmosphere. This allows for the study of various properties of the gases, such as their density, pressure, and reactivity.
To collect a gas using a gas jar, the jar is first filled with water by placing it upside down in a container filled with water. The gas-producing reaction or the gas supply is then placed under the mouth of the jar, causing the gas to displace the water. As the gas rises into the jar, the water level inside gradually lowers, until the jar is filled solely with the collected gas.
Gas jars are commonly used in chemistry experiments, particularly for qualitative and quantitative analysis of gases. They are essential for conducting experiments involving the collection, storage, and manipulation of gases in a controlled and safe manner.
