“Piranha” mixture vs. an apple
Solution that dissolves an apple
A lot of chemists like tropical fish, but unfortunately it’s somewhat problematic to keep them in a laboratory… so they came up with an alternative, the “piranha mixture”, a dangerous and ravenous fish that devours everything in its path!
Reagents and equipment:
- concentrated sulfuric acid;
- concentrated hydrogen peroxide;
- plastic rod.
Pour hydrogen peroxide into the beaker, then carefully add the concentrated sulfuric acid. The “piranha mixture” is ready. Put half an apple in another beaker and pour our mixture over it. Wait!
The mixture of concentrated sulfuric acid and hydrogen peroxide is called “Piranha”. It is one of the strongest oxidizing mixtures in the world. It can eat away almost all organic matter. Sulfuric acid carbonizes food fibers, vitamins and other substances in the apple, turning them into carbon, and hydrogen peroxide oxidizes the carbon to carbon dioxide. With this “simple” method we can feed our predator!
When working with concentrated sulfuric acid and hydrogen peroxide, wear protective gloves, a lab coat and glasses. The mixture is very dangerous, and can leave burns on the skin and eat away clothing.
Warning! Don’t try to repeat this experiment!
