what is sodium carbide
A organic chemical compound that contains the carbide ion (C2-2) and sodium ions (Na+). The chemical formula is Na2C2.
Several carbides are assumed to be salts of the acetylide anion C22â (also called percarbide), which has a triple bond between the two carbon atoms. Alkali metals, alkaline earth metals, and lanthanoid metals form acetylides, e.g., sodium carbide Na2C2, calcium carbide CaC2, and LaC2. Lanthanides also form carbides (sesquicarbides, see below) with formula M2C3. Metals from group 11 also tend to form acetylides, such as copper(I) acetylide and silver acetylide.
