Product Details


CAS NO 144-55-8 99% purity sodium bicarbonate powder used as fire







   Sodium bicarbonate is a chemical compound with the formula NaHCO3. It is a


salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white


solid that is crystalline but often appears as a fine powder. It has a slightly salty,


alkaline taste resembling that of washing soda (sodium carbonate). The natural


mineral form is nahcolite. It is a component of the mineral natron and is found


dissolved in many mineral springs.


























  Loss on drying



















NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous


solution of sodium hydroxide. The initial reaction produces sodium carbonate:


CO2 + 2 NaOH → Na2CO3 + H2O


Further addition of carbon dioxide produces sodium bicarbonate, which at


sufficiently high concentration will precipitate out of solution:


Na2CO3 + CO2 + H2O → 2 NaHCO3


Commercial quantities of baking soda are also produced by a similar method: soda


ash, mined in the form of the ore trona, is dissolved in water and treated with


carbon dioxide. Sodium bicarbonate precipitates as a solid from this method:


Na2CO3 + CO2 + H2O → 2 NaHCO3






  Fire extinguisher



      Sodium bicarbonate can be used to extinguish small grease or electrical fires by


being thrown over the fire, as heating of sodium bicarbonate releases carbon


dioxide. However, it should not be applied to fires in deep fryers; the sudden


release of gas may cause the grease to splatter.Sodium bicarbonate is used in BC


dry chemical fire extinguishers as an alternative to the more corrosive diammonium


phosphate in ABC extinguishers. The alkaline nature of sodium bicarbonate makes


it the only dry chemical agent, besides Purple-K, that was used in large-scale fire


suppression systems installed in commercial kitchens. Because it can act as an


alkali, the agent has a mild saponification effect on hot grease, which forms a


smothering, soapy foam.
