Question

How is ethyne prepared from calcium carbide?

Answer 1

Answer:

Calcium carbide, CaC2, reacts with water to form ethyne, C2H2, and calcium hydroxide. CaC2(s) + 2H2O(l) → C2H2(g) + Ca(OH) 2(s), which volume of ethyne is produced when 6 g of water react completely with CaC2

Answer 2

Ethyne is prepared from calcium carbide by treatment with water.

Explanation:

• The chemical reaction during the preparation of ethyne from calcium carbide.
• $CaC2+2H2O------ Ca(OH)2+C2H2.$
• When calcium carbide reacts with water to form ethyne.
• Partial combustion takes place when ethyne is subjected to reaction with methane.
• Ethyne is prepared by the hydrolysis of calcium carbide where calcium acetylide will be formed.
• A sufficient amount of water is to be added during the process.
