Most people remember the school lessons of chemistry not because boring formulas and the periodic table, and thanks to the fun experiments when mixed Permanganic and Glycerin, as showy appear bright as a result of a chemical reaction flame. Observing precautions, this experience can be made at home.
A little bit about safety
Glycerin is absolutely safe pharmacy drugs used to treat constipation or eliminate dry skin. Dry potassium permanganate is also not dangerous, except that the crystals are left scattered on the surface of the hard output traces. But Permanganic plus glycerol and the resulting mixture becomes fire.
To an interesting experiment is over unplanned fire, you must:
- to prepare a soup plate, tile or other refractory stand;
- remove from the table all flammable objects.
For fire safety must be within reach to put a container of water.
Only ensuring safety can begin to experience conduct.
Beautiful "Volcano Scheele"
needed for the experiment:
- Glycerin (a few drops);
- Potassium permanganate (1-2 pharmacy bags);
- pipette.
Reaction to take place, you must do the following:
- In a bowl or other refractory container to pour pile of potassium permanganate.
- Make the top of the dry mixture with a small recess.
- Using a pipette, add Glycerin potassium permanganate.
Reacting with glycerol, potassium permanganate ignited and burned with the release of water and carbon dioxide. When this appeared violet flame due to the "firing" burning crystals of potassium permanganate, like fireworks or eruption. Experiment results delight children of all ages.
Despite the fact that sparks are extinguished almost immediately in the air, you need to look for response to incident on the paper burning crystal of potassium permanganate did not cause a fire.
But the interaction between the glycerol and potassium permanganate will not happen immediately. Since the addition of glycerol until the fire goes about one minute. To speed up the chemical process, it is recommended to add a few drops of water.
What else can you add
To add some fun chemical experiments, you can do the following:
- Mix glycerin with potassium permanganate, using a glass rod or other non-flammable object. The resulting composition ignited almost immediately, but the flame is steady, without spectacular sparks. This method is used by tourists to make fire without matches.
- Add hydrogen peroxide. Pharmacy liquid is not involved in the inflammation process, and, due to the increased oxygen content will support combustion. Due to peroxide "Volcano" will burn longer.
- Put the napkin on the plate and then pour potassium permanganate and glycerin added. Get a nice fire.
- Mix the aluminum shavings from sawdust and pour over potassium permanganate and then drip Glycerol. During the chemical process shall be burned up not only the dust and magnesium, but also aluminum. Burning will be like fireworks.
Experiments showing children, keep in mind not only produced effect, but also take into account that "young chemists" will want to impress friends by repeating the experiment. To avoid the sad consequences of a fire after a bad experience, older children need explain fire safety rules and tell us what can be dangerous mixture of glycerol Potassium permanganate. Well, from the preschool and primary school component is better to hide in inaccessible places.
