Applications:
Welding and Cutting:
Oxy-Acetylene Welding: Acetylene is commonly used in combination with oxygen to produce a high-temperature flame (around 3,500°C or 6,332°F) suitable for welding and cutting metals. This process is known as oxy-acetylene welding.
Oxy-Acetylene Cutting: The same flame is used to cut through metals in industrial and construction applications.
Chemical Synthesis:

Organic Compounds: Acetylene is used as a raw material in the synthesis of various organic compounds, including acetaldehyde, acetic acid, and synthetic rubber.
Polyvinyl Chloride (PVC) Production: Acetylene is involved in the production of PVC, a widely used plastic.
Lighting:

Carbide Lamps: Historically, acetylene was used in carbide lamps for miners and cavers. These lamps produce light by reacting calcium carbide with water to generate acetylene gas, which is then burned.
Metal Hardening:

Surface Hardening: Acetylene is used in a process called carburization, where it introduces carbon into the surface layer of steel to harden it.
Analytical Chemistry:

Atomic Absorption Spectroscopy (AAS): Acetylene is used as a fuel gas in AAS, a technique for analyzing the concentration of element
