In this lab, students will examine the chemical reaction between baking soda and vinegar, and mix different amounts of these household chemicals to learn about the concept of stoichiometry. Key Concepts: • Stoichiometry is the quantitative balancing of elements in chemical reactions.
4 Ιουλ 2020 · Balanced Chemical Equation for Baking Soda and Vinegar Reaction. One mole of sodium bicarbonate (baking soda) reacts with one mole of acetic acid (from vinegar) to yield one mole of sodium acetate, one mole of water, and one mole of carbon dioxide. The balanced chemical equation is: NaHCO 3 + HC 2 H 3 O 2 → NaC 2 H 3 O 2 + H 2 O + CO 2.
