Sodium bicarbonate is an acid salt and reacts with bases similarly to a neutralization reaction, producing a positive salt and water.

NaHCO? When dissolved in water, NaHCO? ionizes Na" and HCO?-, and HCO?- continues to ionize H" and CO?-, so HCO?- and OH- ionized by sodium hydroxide can undergo a neutralization reaction, producing CO?

Sodium bicarbonate is an acid salt produced by neutralizing a strong base with a weak acid, and is weakly alkaline when dissolved in water. This property allows it to be used as a bulking agent in food preparation. Sodium bicarbonate will leave a residual sodium carbonate after its action, and using too much of it will give the finished product an alkaline flavor.

Extended information:

Decomposes rapidly in a weak acid, and its aqueous solution begins to decompose to give off carbon dioxide and sodium carbonate at 20 degrees Celsius, and decomposes completely by the boiling point. Its solution made in cold water without stirring reacts only slightly alkaline to phenolphthalein paper, and its alkalinity increases with standing or elevated temperature.

The sodium carbonate is placed on the reaction bed and mixed with water, carbon dioxide is blown from below, carbonized, dried, crushed and packaged, and the finished product is obtained.

Na?CO?+CO?+H?O→2NaHCO?

Supplementary: sodium bicarbonate can also be produced by reacting sodium carbonate with insufficient amounts of dilute hydrochloric acid.

Sodium hydroxide can be used as alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; insoluble in propanol and ether. Disproportionation reaction with chlorine, bromine, iodine and other halogens. Neutralizes with acids to produce salt and water.
