Question

When heavy water reacts with calcium carbide, the product formed is:
(A) acetylene
(B) calcium hydroxide
(C) deuterium
(D) deutero acetylene

Answer 1

Hint: In order to find what is the product formed when the calcium carbide reacts with the heavy water, we must have an idea about what type of reaction is taking place. Calcium carbide is having a chemical formula of \[Ca{C_2}\] and it is a present in the solid state.

Complete step by step answer:
Let us now understand about the calcium carbide. Calcium carbide is having a chemical formula of \[Ca{C_2}\] and it is a present in the solid state. Calcium carbide is a colorless and odorless solid. Calcium carbide has a rock-like structure at the room temperature. Calcium acetylide and Phenyl glyceryl ether diacetate are the other names for calcium carbide.
When the calcium carbide reacts with the heavy water the product obtained will be calcium deuteroxide and deutero acetylene. The reaction of the heavy water with calcium carbide is given below:
\[Ca{C_2} + 2{D_2}O \to Ca{(OD)_2} + {C_2}{D_2}\]

Therefore, the correct answer is option (D).

Note:
We have to remember that the calcium carbide has various uses such as:
- Calcium carbide is usually used for the production of acetylene and calcium hydroxide.
- Calcium carbide can also be used as a ripening agent.
- Calcium carbide is used to remove the sulphur from iron and the process is known as desulphurization.
- Calcium carbide is used as the raw material for the production of PVC.
