Question

Ацетилен в лаборатории получают?

Answer 1

Да, смешивают воду и карбид кальция СаС2, они оцень быстро взаимодействуют и выделяется газ-ацетилен

Answer 2

Конечно получают. Вода + карбид кальция = ацетилен

Ca C2 + H2 O -> HC=CH + Ca (OH)2

Answer 3

Obtaining Acetylene in the Laboratory

In the laboratory, acetylene can be obtained through various methods. One common method is the reaction between calcium carbide and water. When calcium carbide reacts with water, it produces acetylene gas and calcium hydroxide. The reaction can be represented by the following chemical equation:

Calcium Carbide + Water → Acetylene + Calcium Hydroxide

This reaction typically occurs at a temperature of around 450-650°C and is often carried out in the presence of a catalyst such as ferrous chloride. The overall process involves several steps, including the preparation of calcium carbide and the controlled reaction with water to yield acetylene gas.

Another method involves the reaction of calcium carbide with various acids, such as sulfuric acid or hydrochloric acid, to produce acetylene gas.

Acetylene can also be obtained through the dehydrohalogenation of vicinal or geminal dihalides using a strong base, such as sodium amide or potassium hydroxide.

These methods demonstrate the versatility of laboratory processes for obtaining acetylene, providing researchers and students with different options for experimental purposes.

It's important to note that safety precautions should always be observed when working with acetylene due to its flammability and potential hazards.
