Sodium bicarbonate (baking soda)
|
| Product name: |
Carbonicacid, monosodiumsalt |
| Physical and chemical properties: |
Sodium bicarbonate is a white monoclinic prismatic crystalline powder or granule. The relative density is 2.20. Odorless, salty.Soluble in water, its aqueous solution is slightly alkaline due to hydrolysis. Do not dissolve in ethanol. Decomposition begins at 65 ° C, and at 270 ° C all CO 2 is evolved and converted to sodium carbonate. Stable in dry air. Slowly decomposes in humid air. pH of the newly configured aqueous solution having a concentration of 0.1 mol/L at 25 ° C is 8.3. |
