Potassium permanganate plus hydrogen peroxide, which can be seen when combining them.Practical experiments show that the way out can turn out to be curious and diverse options if you add improvised homemade facilities. Both drugs are pharmacy, they are easy to buy at an affordable price.
Brief characteristics of substances
Peroxide
Treat peroxides with unstable molecular bonds that are destroyed even without the participation of other chemical compounds.
The product is easily soluble in water, alcohol and other liquids. It is actively oxidized by reacting with organic enzymes, releasing free oxygen and water. The peroxide solution is absolutely transparent, slightly bitter in taste. Used in medicine and industry, it has a concentration of 1 to 98%. Packaged in plastic containers.

Due to its oxygen content, peroxide can be explosive.
In solid form it is produced in tablets with the name "Hydroperite", in addition to peroxide, the product contains urea.
Potassium permanganate
This is what the common people call a chemical compound - potassium permanganate. It is a solid, crystalline substance with a deep purple color, when it is combined with water, it turns crimson. Potassium permanganate dissolves in liquids worse than peroxide, in a ratio of 6.4 g. per 100 ml, it also, under the influence of external factors, decomposes with the release of oxygen.
Unlike hydrogen peroxide, the oxidation reaction proceeds more slowly, therefore, potassium permanganate as an injection is used to treat deep wounds when infected with anaerobic microorganisms. The drug is produced in glass bottles, used for medical and household purposes.
Experiments
Oxygen release
The violent reaction of Peroxide with potassium permanganate is clearly demonstrated in one of the issues of the Galileo channel. Where the leader pours 1 tsp into the flask with peroxide solution. potassium permanganate. The interaction of these substances leads to the release of a fairly large volume of oxygen, which literally "throws out" the liquid from the vessel, from which the smoke "pours like a pipe".
To make sure that there is O2 in the flask, even before the experiment begins, you can set fire to a wooden stick or a long fireplace match and extinguish it. And after the emergence of a "volcano" in a glass flask, lower it there - it starts to burn quite actively!
Conclusion: manganese is a very good catalyst for the release of free oxygen from peroxide solution. If the same experiment is carried out with iodine, the reaction will be completely different. The liquid will gradually become transparent, and an almost black precipitate will fall to the bottom and no O2 will be released.
Solution discoloration
A calmer reaction, in which hydrogen peroxide and potassium permanganate, as well as vinegar essence, participate.
Potassium permanganate dissolves in water (50 grams) until it acquires a bright pink color, then 3 tablespoons of vinegar and 4-re peroxide are poured into it.
Slowly but steadily, the liquid discolors and becomes almost transparent.
Conclusion: if acetic or citric acid and potassium permanganate are mixed with hydrogen peroxide, then with this mixture it is good to neutralize the caustic color of potassium permanganate on hands, plumbing dishes or furniture.
But by combining potassium permanganate with alkalis, such as soda, you can see how the liquid pink solution turns green! Therefore, for the manufacture of cleaning agents, along with peroxide, acidic compounds are often used.
It is interesting that if the experiment is carried out in the reverse order, i.e. add peroxide to the potassium permanganate solution, then the liquid in the glass will first turn brown, and when acid is poured into it, it will also become discolored.
A foam party
Potassium permanganate is added to warm water to a dark purple hue, then liquid soap or dishwashing detergent is placed there and everything is mixed well.
50 ml are poured into this mixture in one motion. 30% hydrogen peroxide. Immediately, a copious thick foam begins to appear from the vessel. So a solution of potassium permanganate and hydrogen peroxide in combination with detergents "generates" a foam fountain.
For a spectacular experience, you can add food colors to the flask and get a rainbow foam.
Invisible
A teaspoon of potassium permanganate is added to a glass with vinegar and the solution is mixed well. It is applied to any inscription made with a ballpoint or ink pen. It disappears, but the paper is colored, so it is wiped with hydrogen peroxide and it takes on its original color. Thus, you can remove the art of your children on valuable books.
In life, the combined use of hydrogen peroxide and potassium permanganate is a rare phenomenon. Considering the properties of these substances when combined, it is recommended to use 100 ml. 3% peroxide and 200 ml. 3% table vinegar, diluted in two liters of water at room temperature, for gastric lavage in case of potassium permanganate poisoning.
This solution helps to reduce its aggressive effect, as it converts permanganate ions into manganese cations (safer for the body).
In industry, potassium permanganate together with peroxide is used in the composition of so-called oxygen bleaches, washing powders and household cleaning products.
