Citric acid endothermic reaction
WebJan 21, 2024 · The crosslinked samples showed an extra shoulder peak at ~220 °C due to an excess of citric acid. The endothermic maximum decomposition peak displayed at 280 °C for salecan presented modifications in the DTG curves registered for the citrate-salecan samples, depending on the amount of citric acid used in the synthesis. 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. The best answer I found was this: Emanuel Manzurola's answer to Is the reaction bicarbonate with citric acid exothermic or endothermic? My teacher an...

The reaction between citric acid and baking soda is a highly safe example of an endothermic reaction, commonly used as a chemistry demonstration.
WebEnergy diagrams for endothermic and exothermic reactions. In the case of an endothermic reaction, the reactants are at a lower energy level compared to the products—as shown in the energy diagram below. In other words, the products are less stable than the reactants. WebWhen the citric acid is added to water, a reaction occurs in which hydrogen ions from the acid are released. These hydrogen ions then react with the baking soda to produce …
