Experiment Set - Böttger Volcano

With the experiment set, the child will learn about the amazing properties of substances, conduct an exciting experiment, and surprise their friends.
«Böttger Volcano» — this is a bright demonstration chemical experiment. It consists of burning ammonium dichromate.
Will help with studies
The... experiment can be used as an example of an oxidation-reduction reaction.
Simple Instructions

Wear gloves. Conduct the experiment in a well-ventilated area. It's better to cover the workspace to avoid getting dirty.
Pour the contents of the packet in a mound into an aluminum dish. Place it on a non-flammable surface, such as something ceramic or on a tile.
Create a depression on top, turning the mound into a small volcano.
Attention: working with fire! Help the child light the resulting volcano with a match and do not leave it unattended during the experiment.
Observe how the self-sustaining exothermic decomposition reaction spectacularly transforms orange ammonium dichromate into green ash.

Result. An oxidation-reduction reaction in which the chromium atom entering into the dichromate anion of the salt takes electrons from the nitrogen atoms contained in the ammonium cation.
The experiment set is intended for children over 5 years old. Children should conduct experiments only under adult supervision.
