Sodium Carbonate Anhydrous

Sodium Carbonate Anhydrous

Sodium carbonate anhydrous is also named soda ash, the typical strong base weak acid salt. The aqueous solution is alkaline. Can react with most of the protonic acid (acidic strong percarbonic acid), the acid is generated when the amount of carbon dioxide, but the amount of sodium bicarbonate (baking soda).
