Acetic Acid-Base Reaction
The results of this experiment generally show the mass of the bottles did not change after the reaction of sodium bicarbonate and vinegar. The reaction is an acid-base reaction, the base being sodium bicarbonate (NaHCO3) and the acetic acid (CH3COOH) in the vinegar. One of the products of this reaction is carbon dioxide, this happens when the hydrogen atom in the acetic acid meets up with the hydrogen and oxygen atoms in the baking soda to form a molecule of water, while the acetate ion (CH3COO) grabs onto the sodium atom and forms a salt, sodium acetate (C2H3NaO2) . The carbon dioxide molecule, free of its other chemical bonds, can now escape, and bubbles forth as a
