Sodium Bicarbonate and Hydrochloric Acid
NaHCO3 + HCl → NaCl + H2O + CO2
概要
Sodium bicarbonate (baking soda) reacts with hydrochloric acid to produce sodium chloride, water, and carbon dioxide gas. The bicarbonate ion acts as a base, accepting a proton to form carbonic acid, which immediately decomposes to water and CO₂. The effervescence is characteristic of bicarbonate-acid reactions.
