6. Question & Answer
  • Here is the reaction: CaC₂(s) + 2H₂O(l) → Ca(OH)₂(s) + C₂H₂(g) This industrial reaction nowadays has been superseded by other methods, so that the use of calcium carbide has been steadily dropping during the last twenty years. When it is used to produce acetylene, however, it is mixed with sand be...
  • I have an old lantern that runs on calcium carbide and water. The acetylene gas produced is ignited by a match and produces a weak, sooty flame. When I was young, my dad used to fire up the lantern. I still recall the unique smell produced and my fascination with producing a fuel from water. It was...
  • It is the original method of ripening fruits that were plucked green, These were mangos and banana. Calcium carbide was once very common in villages for lamp light. I guess someone accidentally found out that calcium carbide triggers ripening. However, the fruits don’t taste right. The skin of the...
  • A pretty genuine doubt, even I had this doubt when I first saw this formula. The answer lies in the fact that carbon can form bond with other carbon atoms, I guess you can guess the answer now In calcium carbide the carbide ion is an acetylide ion (C2)- in which two carbon atoms are joined by a tri...
