One of the best-known home experiments for children is the volcano experiment. The success of the volcano experiment is based on the fact that it is simple, safe and colorful. Behind this simple experiment hides very important theoretical basis of chemistry, acid base reactions. You can see it below this entry.
HOW TO DO THE EXPERIMENT OF THE VOLCANO
Materials for the experiment:
1) Citric acid (or vinegar).
2) Sodium bicarbonate.
Additionally you can use auxiliary materials such as:
1) Test tubes.
2) Laboratory rack.
3) Food dyes.
4) Pipette.
Step by step experiment:
The experiment of the volcano consists of mixing citric acid (or vinegar) with sodium bicarbonate and see how a reaction is generated where CO2 is released and therefore a very showy reaction is generated.
1) Introduce a little citric acid into a test tube (or glass)
2) Sodium bicarbonate in the same proportion in the test tube (or glass)
3) In parallel in another test tube, or glass, pour water and (optionally) put some food coloring dyes to give it color.
4) Pour the water over the mixture of citric acid and baking soda.
5) Wait, have fun and re-make changing the color and changing the proportions.
NOTE: If you are going to use vinegar instead of citric acid, you may not need water and pouring the baking soda directly on the vinegar will generate the reaction.
Vinegar leaves much more odor and dirtier than citric acid, that's why we use citric acid here.
