In this activity: Students conduct a reaction with citric acid and baking soda in a universal indicator solution. The resulting chemical reaction produces a gas, causes a color change with an ...

Remind students that citric acid and baking soda are called the reactants in this chemical reaction. Reactants are the chemicals that are mixed together and interact during a chemical reaction. Carbon ...

They’re called endothermic reactions. If you take some citric acid solution and combine it with baking soda, we can see the reactants fizzing away. And the surrounding flask feels cold.

“When using AHAs such as citric acid, you must keep the skin’s protective barrier healthy in order to avoid any adverse ...

to overcome before the reaction can proceed. Cells generate energy from the controlled breakdown of food molecules. Learn more about the energy-generating processes of glycolysis, the citric acid ...
