Calcium carbide formula

In Calcium carbide—the country’s main mineral export—limestone, dolomite, gypsum, coal, marble, quartzite, and talc are the primary products of the country’s mining activities. Other minerals, extracted in smaller quantities, include slate, beryl, pyrite, and various gemstones, as well as a number of metals, such as lead,… calcium • In …material in the production of calcium carbide, CaC 2, also known simply as carbide, or calcium acetylide. Colourless when pure (though technical grades are typically grayish brown), this solid decomposes in water, forming flammable acetylene gas and calcium hydroxide, Ca(OH) 2. The decomposition reaction is used for the production of acetylene, which… classification of carbides • In …important of these compounds is calcium carbide, CaC 2. The primary use for calcium carbide is as a source of acetylene for use in the chemical industry. Calcium carbide is synthesized industrially from calcium oxide (lime), CaO, and carbon in the form of coke at about 2,200 °C (4,000 °F). Pure…

Physical observations during the reaction of calcium carbide and water Calcium hydroxide is also formed as a product and it exist as a aqueous colourless solution. If concentration of calcium hydroxide is high, calcium hydroxide can be precipitated as a Safety during the reaction You should be very careful to not expose a open flames or any high temperatures to emitting acetylene gas because acetylene is a highly flammable gas. Uses of CaC 2 and H 2O reaction Acetylene gas is used for ripping fruits. However, this is illegal in some countries because several toxic compounds such as phosphine and arsine are generated. But, these toxic gases can be removed by passing acetylene gas through

Calcium Carbide By the reaction of calcium carbide and tritiated water, tritium-labeled acetylene can be prepared, which can be a starting material in many organic syntheses.

The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22g/cc and it melts at 2160°C with a boiling point (under an inert atmosphere) of 2300°C, where it decomposes. Its main use industrially is in the production of acetylene and calcium cyanamide, CaCN 2. Calcium carbide is produced industrially in an electric-arc furnace from a mixture of CaCO 3 and coke (carbon) at approximately 2000°C. This method has not changed since its invention in 1888: CaCO 3+3C⇒CaC 2+CO+CO 2 The high temperature required for this reaction is not practically achievable by traditional combustion, so the reaction is performed in an electric-arc furnace where the electrodes are graphite. The carbide product produced generally contains around 80–85% calcium carbide by weight. The carbide is crushed to produce small lumps that can range a few millimeters up to 50mm. The impurities are concentrated in the finer fractions. The CaC 2 content of the product is assayed by measuring the amount of acetylene pro...
