Tianjin Red Triangle shelf baking soda

Sodium bicarbonate (NaHCO?) (Sodium Bicarbonate), white fine crystals, solubility in water of less than sodium carbonate. Is an industrial chemical, there may be toxic. Solid above 50 ℃ began to decompose to sodium carbonate, carbon dioxide and water, completely decomposed at 440 ℃. Acid salt sodium bicarbonate is a strong base and weak acid during and after the generated weakly alkaline when dissolved in water. This feature allows it to be used as food production process of leavening agent. Sodium bicarbonate, sodium carbonate may remain in effect after using too much can make the finished product has a base flavor. Chinese name of sodium bicarbonate English name Sodium Bicarbonate aka baking soda, sodium bicarbonate, sodium acid, heavy Cao chemical formula NaHCO? Molecular Weight 84.01 CAS Registry Number 144-55-8 EINECS Accession No. 205-633-8 melting point 440 ℃ decomposition of water-soluble 7.8g / 100ml, 18 ℃ density of 2.159 g / c? (Solid) Appearance white powder or monoclinic crystalline powder physical properties editor of sodium bicarbonate as white crystals, or slightly opaque monoclinic crystal. 2.15 specific gravity. Their solution was slightly alkaline due to hydrolysis, stable at room temperature in nature, heat easily decompose at above 50 ℃ gradually decompose at 440 ℃ completely lose carbon dioxide, no change in dry air, humid air in slow decomposition. Solubility: Soluble, 18 ℃; 16.0g, 60 ℃. 2 Chemical Properties editor heat decomposition. Slow decomposition in moist air. About starting at 50 ℃ reaction of CO ?, at 100 ℃ all into sodium carbonate. Rapid decomposition in weak acid in aqueous solution at 20 ℃ begins to decompose carbon dioxide and sodium carbonate, to a boiling point when all of decomposition. No agitation was its cold water made of phenolphthalein test paper was only slightly alkaline reaction, place or elevated temperatures in the basic increase. PH 25 ℃ freshly prepared 0.1mol / L aqueous solution is 8.3. Low toxicity, the median lethal dose (rat, oral) 4420mg / kg. After the consumption of soda editor Unlike industrial base of soda ash (sodium carbonate) and baking soda (sodium bicarbonate), baking soda to absorb carbon dioxide from the soda solution or a crystal made of sodium bicarbonate preparation. Therefore, the baking soda in some places also known as the food base (powder form). Baking soda in a solid state, circular, color white, soluble in water. Single salt as: normal salt, acid salt, basic salt, acid salt is sodium bicarbonate and a weak acid and a strong base after the generated weakly alkaline when dissolved in water. When mass production bread, fritters and other foods, often baking soda mix surface melt water, the decomposition into sodium carbonate heat, carbon dioxide and water, carbon dioxide and water vapor overflows can cause food more fluffy, sodium residues in food . For example, commonly known as the North "; alkali bun"; adding an excess of soda can taste out. Sodium bicarbonate, commonly known as "baking soda" work for food ferment, soft drinks and cold carbon dioxide generating agent, preservative butter. It can be directly used as raw materials in the pharmaceutical industry for the treatment of hyperacidity. Can be used for film production, tanning, dressing, smelting, metal heat treatment, as well as for fiber and rubber industries. Food industry of one of the most widely used bulking agent. Dyeing and printing and dyeing industry as a fixing agent, pH buffering agents, fabric finishing post-treatment agent. Raw pharmaceutical industry as antacids. Unlike industrial base made of soda ash (sodium carbonate) and baking soda (sodium bicarbonate), baking soda to absorb carbon dioxide from the soda solution or after crystallization. Therefore, the baking soda in some places also known as the food base (powder form). Baking soda in a solid state, circular, color white, soluble in water. It refers to the distinct industrial base made of soda (sodium carbonate) and baking soda (sodium bicarbonate), baking soda to absorb carbon dioxide from the soda solution or after crystallization. Therefore, the baking soda in some places also known as the food base (powder form). Baking soda in a solid state, circular, color white, soluble in water.
