Calcium Carbide Extra Pure is a high-purity inorganic compound primarily used in laboratories for the generation of acetylene gas through hydrolysis, making it valuable for gas evolution experiments and flame tests. It is also utilized in organic synthesis reactions where acetylene is required as a precursor. The extra pure grade ensures minimal impurities, which is essential for consistent reaction performance and accuracy in analytical or instructional settings. Due to its high reactivity with water and release of flammable gases, it must be handled with care under dry conditions and stored in tightly sealed, moisture-resistant containers away from heat sources.

Description

Calcium Carbide Extra Pure

Primary Uses 

  1. Acetylene Gas Generation

    • Reacts with water to produce acetylene (C₂H₂) gas:
       CaC2+2H2O→C2H2+Ca(OH)2\text{CaC}_2 + 2\text{H}_2\text{O} \rightarrow \text{C}_2\text{H}_2 + \text{Ca(OH)}_2CaC2​+2H2​O→C2​H2​+Ca(OH)2​
    • Commonly used in demonstrations, gas collection experiments, and flame testing.

  2. Qualitative Gas Tests

    • Used in student and teaching labs to show combustion of unsaturated hydrocarbons, including sooty flame characteristics of acetylene.

  3. Source of Acetylene for Organic Synthesis

    • In advanced labs, acetylene generated from calcium carbide can be used as a starting material in the synthesis of vinyl compounds, alcohols, or aldehydes.

Secondary Uses

  1. Demonstrations in Chemistry Education

    • Ideal for visual and audible reactions, showcasing vigorous gas evolution and flammability—useful in school or college-level demonstrations.

  2. Study of Alkynes

    • Offers an inexpensive, hands-on method to produce alkynes in situ for analytical chemistry or spectroscopic studies.

  3. Calibration of Gas Sensors or Detection Equipment

    • Occasionally used as a controlled acetylene source to calibrate or test gas detectors in lab setups.
