Odorless, taste salty, soluble in water. 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, 7.8g, 18 ℃; 16.0g, 60 ℃. Baking soda and chemical properties: 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. Dissolved in 10 parts of water at 25 ℃, about 18 ℃ when dissolved in 12 parts of water, insoluble in ethanol. 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. The reaction with the acid reacting with HCl:??? NaHCO + HCl ==== NaCl + H O + CO ↑ and CH COOH reaction:? NaHCO + CH COOH ==== CH COONa + H O + CO????? ↑ with a base and sodium hydroxide: NaHCO + NaOH ==== Na CO + H O and calcium hydroxide:???? bicarbonate dose should be divided and a small amount of excess.

[2] Safety phrases Avoid contact with skin and eyes. Baking soda and a wide range of applications: sodium bicarbonate 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. Both as wool detergent, as well as for agriculture seed soaking. Food industry of one of the most widely used bulking agent for the production of biscuits, cakes, bread, bread, soft drinks are carbon dioxide generating agent; alkaline compound with alum baking powder, soda ash may be complex for civil stone base; also be used as preservative butter. Fire equipment for the production of acid fire extinguisher and foam extinguishers. Rubber industry use it with alum, H hair pore forming agent with the role played even made holes for rubber, sponge production. Metallurgical industry for ingot casting flux. Machinery industry as steel (foundry) sand forming additives. Dyeing and printing and dyeing industry as a fixing agent, pH buffering agents, fabric finishing behind treatment agent. Dyeing can be prevented by adding baking soda to produce color flowers bobbin. Raw pharmaceutical industry as antacids
