Sodium Bicarbonate and Acetic Acid (Vinegar Volcano)
NaHCO3 + CH3COOH → CH3COONa + H2O + CO2
Visão geral
Baking soda reacts with vinegar to produce sodium acetate, water, and carbon dioxide gas. This endothermic reaction absorbs heat, making the mixture slightly cooler. The vigorous fizzing from CO2 is one of the most widely performed kitchen chemistry experiments.
