    Citric Acid and Sodium Carbonate Reaction.
    Citric acid and sodium carbonate undergo a chemical reaction to form sodium citrate and carbon dioxide gas. The balanced chemical equation for this reaction is:
    C6H8O7 + 3Na2CO3 → 2C6H5O7Na3 + 3CO2。
    Mechanism of the Reaction:
    The reaction between citric acid and sodium carbonate is an acid-base reaction. Citric acid is a weak organic acid, and sodium carbonate is a strong base. When these two compounds are mixed, the hydrogen ions (H+) from citric acid react with the hydroxide ions (OH-) from sodium carbonate to form water (H2O). This reaction results in the formation of sodium citrate and carbon dioxide gas.
    Uses of the Reaction:
    The reaction between citric acid and sodium carbonate has several practical applications. It is used in the food industry as an acidulant and buffering agent. Sodium citrate is used as a flavor enhancer and preservative in a variety of foods and beverages. Carbon dioxide gas is used as a leavening agent in baking and as a propellant in carbonated beverages.
    Other Reactions of Citric Acid:
    In addition to reacting with sodium carbonate, citric acid can also react with other bases, such as sodium hydroxide and potassium hydroxide. These reactions also produce sodium citrate and carbon dioxide gas. Citric acid can also react with metals, such as iron and aluminum, to form metal citrates. These reactions are used in the production of metal coatings and pigments.
