Ürün Açıklaması

Sodium bicarbonate (chemical formula: NaHCO3), commonly known as baking soda, baking powder, carding powder (Hong Kong, Taiwan), heavy cao, baked alkali, etc., white fine crystals, solubility in water is less than soda.
odium bicarbonate, a white alkaline powder that is easily soluble in water, begins to act after binding with water to release carbon dioxide CO2, reacts faster in acidic liquids (such as fruit juice), and as the ambient temperature increases, the faster the release of gases.
Sodium bicarbonate will remain sodium carbonate after action, and excessive use will make the finished product have an alkaline taste.
The aqueous sodium bicarbonate solution is weakly alkaline, commonly known as baking soda and baked alkali.
 

 

Chemical properties
It is easy to decompose when heated. Decomposes slowly in humid air. The reaction starts at about 50 °C to form CO2, and at 100 °C it all becomes sodium carbonate. Rapid decomposition in weak acids, its aqueous solution at 20 ° C began to decompose carbon dioxide and sodium carbonate, to the boiling point when all decomposed. Soluble in 10 parts water at 25 °C, soluble in 12 parts water at about 18 °C, insoluble in ethanol. Its solution made of cold water without agitation, the phenolphthalein test strip is only slightly alkaline reaction, placed or increased temperature, its alkaline increases. The pH of the freshly prepared 0.1 mol/L water soluble solution at 25 °C is 8.3. Low toxicity, half of the lethal amount (rats, oral) 4420 mg/kg.

Dry, protect from light, sealed and stored.
Analytical reagents. Organic synthesis. Pharmaceutical (treatment of hyperacidity). Starter culture (baked pastry). Fire extinguishing agent (foam or dry powder).
pH greater than 7, predominantly alkaline, but does not contain OH-, does not belong to alkalis, and belongs to acid carbonates (bicarbonates).
