Question

How to produce Acetylene from Calcium carbide.

Answer 1

Hint :Acetylene is created by any of three methods: by reaction of water with calcium carbide, by section of a hydrocarbon through an electric circular segment, or by incomplete combustion of methane with air or oxygen.

Complete Step By Step Answer:
Acetylene $ \left( {{C}_{2}}{{H}_{2}} \right) $ is the world's generally proficient and most burning consuming standard welding gas. For creating acetylene, the reaction of calcium carbide $ \left( Ca{{C}_{2}} \right) $ with water $ \left( {{H}_{2}}O \right) $ is utilized, though acetylene and lime milk $ Ca{{\left( OH \right)}_{2}} $ is produced.
Calcium carbide $ \left( Ca{{C}_{2}} \right) $ reacts with water to form acetylene $ \left( {{C}_{2}}{{H}_{2}} \right) $
Preparation of acetylene from calcium carbide: Acetylene might be produced by the chemical reaction between calcium carbide and water. This reaction produces a lot of heat, which must be eliminated to prevent the acetylene gas from exploding. There are a few varieties of this process wherein either calcium carbide is added to water or water is added to calcium carbide.
 $ CaC{{O}_{3}}\to CaO+C{{O}_{2}} $
 $ CaO+3C\to Ca{{C}_{2}}+CO $
Both of these varieties are called wet processes due to an excess amount of water being utilized to absorb the heat of the reaction. A third variety, called a dry process, utilizes just a limited amount of water, which at that point evaporates as it retains the heat.
 $ Ca{{C}_{2}}+2{{H}_{2}}O\to Ca{{\left( OH \right)}_{2}}+{{C}_{2}}{{H}_{2}} $
This $ Ca{{C}_{2}} $ is formed by heating coke with lime in an electric furnace. Then $ \left( Ca{{C}_{2}} \right) $ with water generates acetylene $ \left( {{C}_{2}}{{H}_{2}} \right) $ gas.

Note :
Calcium Carbide reacts with water and moisture to produce flammable Acetylene gas and Lime. The heat of the reaction may ignite the Acetylene. Applications of calcium carbide incorporate manufacture of acetylene gas, and for production of acetylene in carbide lamps; assembling of chemicals for compost; and in steelmaking.
