NaHCO3 + HC2H3O2 -> NaC2H3O2 + H2O + CO2

Question

Student mixes baking soda and acetic acid to produce a chemical reaction shown what reaction happens

Answer 1

The reaction you've mentioned is between sodium bicarbonate (baking soda, NaHCO3) and acetic acid (HC2H3O2, or vinegar). When these two substances react, they undergo an acid-base reaction that produces sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide (CO2) gas.

Here's a breakdown of the reaction:

1. Reactants:

   • Sodium bicarbonate (NaHCO3) is a weak base.
   • Acetic acid (HC2H3O2) is a weak acid.

2. Reaction:

   • The sodium bicarbonate neutralizes the acetic acid, leading to the formation of sodium acetate in solution, water, and carbon dioxide gas.
   • The gas produced is what causes bubbling or fizzing during the reaction.

3. Products:

   • Sodium acetate (NaC2H3O2), which is a salt.
   • Water (H2O).
   • Carbon dioxide gas (CO2).

This reaction is commonly demonstrated in chemistry classes and is frequently used in cooking (especially in recipes involving baking soda and vinegar). It is an example of an acid-base reaction that produces a salt and gas.
