The reaction between sodium bicarbonate (NaHCO₃) and acetic acid (CH₃COOH) is a form of neutralization reaction. The acid neutralizes the sodium bicarbonate which is a base, and in this process CO₂ gas is liberated.
The equation for the reaction between acetic acid and sodium bicarbonate is as follows:
CH₃COOH + NaHCO₃ ---------------------> NaC₂H₃O₂ + H₂O + CO₂
The answer is d) formation of bubbles of a colourless and odourless gas - which is the CO₂ gas that is produced.
