The usual laboratory method for making acetylene is by adding (dropwise) water to calcium carbide:

CaC2 + 2 H2O → C2H2 + Ca(OH)2

Calcium carbide is very cheap and available without restrictions in most countries.

What does acetone absorb in acetylene tanks?

Acetone is used in acetylene tanks to absorb and stabilize acetylene gas. It acts as a solvent that helps dissolve acetylene, allowing for safer storage at higher pressures. By absorbing acetylene, acetone prevents the gas from becoming too concentrated, which could lead to instability or detonation. This combination helps ensure the safe handling and transport of acetylene.


Can you mix helium and acetylene?

It is not recommended to mix helium and acetylene as they have different physical and chemical properties. Helium is an inert gas while acetylene is a flammable gas. Mixing them could create a hazardous situation due to the risk of combustion or explosion.


Why do acetylene cylinders contain acetone?

Acetylene cylinders contain acetone to stabilize the acetylene gas and prevent it from exploding. Acetylene is highly volatile and can decompose explosively under pressure; by dissolving it in acetone, the gas can be safely stored at higher pressures. The acetone acts as a solvent, allowing a larger volume of acetylene to be contained within the cylinder. This ensures safe handling and transportation while maintaining the effectiveness of the gas for various applications.


How is tetrabromoethane prepared from acetylene?

Tetrabromoethane can be prepared from acetylene through a process of halogenation. Initially, acetylene (C₂H₂) is reacted with bromine (Br₂) in a non-polar solvent, resulting in the formation of dibromoethene (C₂H₂Br₂). This intermediate can then undergo further bromination to yield tetrabromoethane (C₂Br₄). The overall reaction involves the addition of bromine across the triple bond of acetylene, effectively saturating it with bromine atoms.

How is hydrogen gas prepared in the laboratory?

Hydrogen gas can be prepared in the laboratory through the reaction of a metal (such as zinc or aluminum) with an acid (such as hydrochloric acid). The metal reacts with the acid to produce hydrogen gas as one of the products. This method is safe and commonly used for producing hydrogen gas on a small scale in the laboratory.
