Question: what is the chemical equation for citric acid and baking soda?
Answer: Citric acid is an organic molecule with three carboxylic acid groups. Each one of these will react with one molecule of sodium bicarbonate, so you will need three moles of sodium bicarbonate for each mole of citric acid. C3H5O(COOH)3 + 3NaHCO3 → C3H5O(COONa)3 + 3H2CO3.
