Pandai Lab 7 : Volcano Experiment

Have you tried the volcano experiment at school or home? Here, Pandai Lab 7 brings you to make volcano experiments using lemons! It is awesome, right? This lemon volcano can create something really beautiful incorporating all the colours of the rainbow. 

On 10 November 2020, Pandai will bring you to do an epic experiment. This lemon volcano experiment is no exception and is a colorful, hands-on way to explore early chemistry concepts. It was so much fun. Here the details for experiment:

Date: 10 November 2020
Title: Volcano Experiment
Materials: lemons, spoon, fork, food colouring & baking soda.


1. Cut the top and bottom off the lemon so it stands upright. 
2. Use a spoon to break up/partially scoop out the inside of the lemon. 
3. Pour some baking soda on top of the lemon. 
4. Use a fork to mix the baking soda with the inside of the lemon.
5. Keep mixing with the fork periodically, and adding more baking soda, until the reaction stops.

What makes this possible and happened?

This experiment is a volcano. The reaction is the same as a lemon volcano with chemical reaction and concepts. So, when we add baking soda to the lemon, we’re combining citrus acid with sodium bicarbonate, which forms a gas called carbon dioxide. What we’re seeing is a chemical reaction between an acid and a base. lemon juice contains citric acid which when mixed with the base, baking soda (sodium bicarbonate), reacts to form carbon dioxide and sodium citrate which causes the liquid to fizz and bubble. Once the citric acid and the baking soda have neutralized each other, the reaction stops, so eventually your volcano will stop erupting.
