Difference Between Sodium Carbonate and Sodium Bicarbonate
Sodium carbonate, chemical name is soda/soda ash, chemical formula is Na2CO3. Usually white powder or fine-grained crystal, odorless, strong water absorption, easy to agglomerate. High temperature decomposition, easily soluble in water, the aqueous solution is alkaline. Although soda is also known as soda ash or caustic soda, it is a salt, not a base. It got its name because when soda is dissolved in water, the aqueous solution is alkaline. Sodium carbonate is widely used in chemical, pharmaceutical, metallurgy, ceramics, rubber, machinery, printing and dyeing and other industries, and is a chemical raw material that we cannot obtain. In daily life, we can see sodium carbonate in the kitchen. It is generally used to wash oil stains, and it is also added when making steamed buns and buns. Sodium bicarbonate, chemical name is baking soda, chemical formula is NaHCO3. Usually white crystalline powder, odorless, easily soluble in water. It decomposes slowly in moist or hot air, producing carbon dioxide. Easily decomposed by heat. It is completely decomposed when heated to 270 ° C, and the decomposition products are sodium carbonate, water and carbon dioxide. Sodium bicarbonate is also widely used, which is basically the same as the industry where sodium...
