Science at Home: Lemon Volcano

Creating a fake volcano gives us an idea of how a volcano looks like when the lava erupts. This is a simple classic science experiment works based on a chemical reaction and showing physical volcano eruption. The chemical reaction between baking soda and vinegar is said to be an 'Acid-Base Reaction'. Because the chemical reaction is happening between the acetic acid (vinegar) and a base (sodium bicarbonate). The acetic acid (a weak acid) reacts with and neutralizes the base (sodium bicarbonate). The gas released during the reaction is the carbon dioxide. Carbon dioxide is the main culprit for the fizzing and bubbling of the wonderful 'eruption'.
