Reactants

The chemical equation for the reaction of vinegar with baking soda. Acetic acid, which is found in vinegar, reacts with sodium bicarbonate (baking soda) to yield sodium acetate, water, and carbon dioxide.
  • Vinegar is acetic acid (C2H4O2) and water. Acetic acid is made of 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms.
  • Baking soda is sodium bicarbonate (NaHCO3). Sodium bicarbonate is made of 1 sodium ion, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.

Products

The chemical equation for the reaction of vinegar with baking soda. Acetic acid, which is found in vinegar, reacts with sodium bicarbonate (baking soda) to yield sodium acetate, water, and carbon dioxide.
  • One of the products of the vinegar and baking soda reaction is sodium acetate (NaC2H3O2).
  • Sodium acetate is made of 1 sodium ion, 2 carbon atoms, 3 hydrogen atoms, and 2 oxygen atoms.
  • The other products are water(H2O) and carbon dioxide (CO2).

Mass is Conserved

Space filling models of the molecules representing the products and reactants in the reaction between baking soda and vinegar are shown on a scale to indicate that the equation is “balanced”. The same amount and kinds of atoms are on both sides of the equation.
  • All of the atoms in the reactants are in the products.
  • The mass of the reactants and products is the same.

Controlling Amount of Products Formed

The chemical equation for the reaction of vinegar with baking soda. Acetic acid, which is found in vinegar, reacts with sodium bicarbonate (baking soda) to yield sodium acetate, water, and carbon dioxide.
  • Adding more of one reactant will make more products as long as there is still enough of the other reactant to react.
  • If you add more and more of one reactant the other will eventually run out and no more products will be formed.
