At what pressure is dissolved acetylene stored?

Dissolved acetylene is typically stored at a pressure between 250 psi and 300 psi. The correct choice reflects the standard pressure at which acetylene gas is dissolved in acetone and stored within specialized cylinders. This pressure range is crucial because acetylene needs to be dissolved in a solvent (such as acetone) to stabilize it and prevent it from undergoing decomposition, which can occur if stored in a pure gaseous state at higher pressures.

The higher pressure allows for sufficient stabilization and ensures safe handling and transportation. Understanding the storage requirements for acetylene is critical in welding and cutting applications, as it influences both the safety and effectiveness of the gas when used as a fuel source in torches.
