Calcium Carbide- 1 Kg Packs

Calcium Carbide is an inorganic compound composed of calcium and carbon, with the chemical formula CaC₂ and a formula mass of approximately 64.10 g/mol. It is commonly encountered as greyish-black crystals or dark irregular lumps and belongs to the carbide family of compounds. Calcium carbide reacts vigorously with water or moisture, producing acetylene gas and calcium hydroxide, making its chemical reactivity an important subject in industrial chemistry and specialised laboratory investigations. It is relevant to studies of inorganic compounds, carbide chemistry, and gas-forming reactions conducted under professionally controlled conditions. This 1 kg pack is listed for laboratory sourcing, subject to confirmation of the supplied grade, composition, and physical form. Because contact with water can release highly flammable gas and create a fire or explosion hazard, calcium carbide requires strict moisture exclusion, appropriate engineering controls, and handling by trained personnel.

Key Features of Calcium Carbide

• Defined inorganic composition: Calcium carbide has the formula CaC₂ and contains calcium and carbon in a 1:2 atomic ratio.
• Distinctive physical appearance: It is commonly described as a greyish-black crystalline material or dark irregular solid, depending on its physical form.
• High chemical reactivity: Contact with water produces acetylene gas and calcium hydroxide, demonstrating its characteristic carbide chemistry.
• Gas-forming reaction: Its reaction with water is relevant to the study of chemical reactions that generate gases, although such reactions require specialist controls because acetylene is highly flammable.
• Specialised laboratory relevance: It may be considered for approved inorganic chemistry investigations when the method, product specifications, and safety arrangements are appropriate.

Laboratory Applications of Calcium Carbide

• Inorganic chemistry studies: Relevant to specialised investigations of metal carbides, their composition, and their chemical reactivity.
• Reaction chemistry research: Studied to understand the reaction of carbides with moisture and the formation of acetylene and calcium hydroxide under controlled professional conditions.
• Gas-generation chemistry: Can be examined in appropriately equipped facilities as an example of a gas-forming inorganic reaction, subject to rigorous fire and explosion controls.
• Industrial chemistry investigations: Relevant to research into the chemistry of acetylene production and the industrial reactions of calcium carbide.
• Materials chemistry: May be considered in specialised investigations involving carbide materials and their chemical behaviour when supported by suitable technical procedures.

Why Choose Lab Wale to Buy Calcium Carbide

Lab Wale offers a sourcing option for laboratory chemicals and scientific supplies used by universities, research centres, and laboratory professionals. When purchasing Calcium Carbide in a 1 kg pack, buyers should confirm the chemical identity, applicable grade, physical form, and available technical and safety documentation. Because this substance reacts dangerously with moisture and releases flammable acetylene gas, the intended application, storage arrangements, and handling controls must be evaluated before purchase. Appropriate product selection helps laboratories assess whether the material meets their technical and safety requirements.

Frequently Asked Questions About Calcium Carbide

What is Calcium Carbide used for in laboratories?

Calcium carbide is relevant to specialised inorganic chemistry and industrial chemistry investigations involving carbide reactivity and acetylene formation. It may be studied in appropriately equipped facilities under strict professional controls. Its water reactivity and associated fire and explosion hazards make it unsuitable for routine unsupervised classroom demonstrations.

What are the chemical formula and molecular weight of Calcium Carbide?

Calcium carbide has the molecular and empirical formula CaC₂ and a formula mass of approximately 64.10 g/mol. These values refer to pure calcium carbide. Commercial material may contain impurities or other constituents, so its actual composition must be confirmed when precise stoichiometric calculations are required.

What is the CAS number of Calcium Carbide?

The CAS Registry Number for calcium carbide is 75-20-7. This identifier distinguishes calcium carbide from other calcium compounds, including calcium carbonate and calcium acetate. Confirm the product identity against the applicable technical documentation before recording the substance in a laboratory inventory or selecting a procedure.

Why must Calcium Carbide be protected from water?

Calcium carbide reacts with water to form calcium hydroxide and acetylene gas. Acetylene is highly flammable and can create a fire or explosion hazard. Even moisture can initiate a dangerous reaction, so the substance requires dry, sealed storage and specialist handling that prevents contact with water.

How should Calcium Carbide be stored and handled safely?

Store calcium carbide in an airtight, moisture-resistant container in a dry, secure area, segregated from water and incompatible substances. Prevent contact with damp air, avoid dust generation, and eliminate ignition sources. Handling should be restricted to trained personnel following the applicable Safety Data Sheet and approved procedures for reactive chemicals.

Storage Conditions for Calcium Carbide

Store Calcium Carbide in an airtight, moisture-resistant, compatible container in a dry, secure, well-ventilated storage area. Protect it rigorously from water, humidity, and other sources of moisture. Keep it away from incompatible substances and ignition hazards associated with possible acetylene release. Follow the product-specific Safety Data Sheet and institutional procedures for water-reactive chemicals.

Precautions for Handling Calcium Carbide

Review the current Safety Data Sheet and complete a specialist risk assessment before handling. Calcium carbide reacts with water to release highly flammable acetylene gas and can cause fire or explosion. Prevent all contact with water and moisture, avoid inhaling dust, and use appropriate protective equipment and suitable engineering controls. Keep ignition sources away, and use only approved procedures for reactive chemicals. Emergency response, spill management, and disposal must be handled by trained personnel using methods specifically suitable for water-reactive substances; never apply water directly to the material.
