Chemical Reactions And Equations: Magic Volcano

[Submitted By: Manusree Of Grade 10, JHCS Kondapur School]


Ok guys,

So today we are going to be looking at an experiment so famous, that it has become synonymous with the subject of chemistry. I am of course talking about the Volcano Experiment.

Let's take a look at how it's done.

For this experiment you will need

- 10 mL Oil

- 20 mL Water

- Red Cabbage Powder ( For The Bright Red Colour)

- Citric Acid Powder

-Baking Soda


Step 1:- Take the red cabbage powder and mix it in a beaker with the baking soda

Step 2:- Add in some oil and some water

Step 3:- Shake the container well and you should see a violent reaction


Let us take a look at what exactly happened

Now, in this reaction the main ingredients that are reacting are the baking soda and the citric acid. This is a neutralisation reaction between an acid and a base, baking soda which is a base and citric acid.

When citric acid and baking soda react they form CO2

Here's the reaction that takes place.

C6H8O7 + NaHCO3 =====> H2O + CO2 + Na3C6H5O7

Here, we can see that a CO2 is released, this in turn, aerates the entire solution into a foamy reaction which resembles a volcano.


Thanks for reading this post!
