Citric acid endothermic reaction
WebMar 4, 2024 · heat associated with three chemical reactions. The first system we will study is the reaction between citric acid and sodium hydrogen carbonate (sodium bicarbonate). Citric acid possesses three acidic protons and reacts with three sodium bicarbonate molecules. This reaction is endothermic ( H > 0): H. 3. C. 6. H. 5. O. 7 (aq) + 3NaHCO. … WebAnswer (1 of 3): I did some googling to figure out what you are talking about. This is obviously a common classroom experiment to teach something.
