Decomposition of hydrogen peroxide by potassium permanganate. In this experiment, potassium permanganate is reduced by hydrogen peroxide to manganese oxide (IV), which catalyzes the decomposition of hydrogen peroxide. This produces a large amount of heat that causes the water to boil and emit a large amount of oxygen. 2KMnO4 + = 2H2O + 3H2O2 2MnO2 + KOH + 3O201:041080p 394 01:04Chemical reaction - Decomposition of Hydrogen peroxide by potassium permanganate 1080p

Potassium nitrate is a colorless or white crystalline solid. Its melting point is 334 ° C. When heated to 400 ° C decomposes to oxygen and potassium nitrite. Potassium nitrate is an oxidizing agent. For this reason, its main use was to produce black powder. Currently used in pyrotechnics as an oxidant, such as to produce pulses or short and very light pulses generated during the combustion of a mixture of fine particles of metal nitrate. When mixed with a saccharide such as sucrose, in stoichiometric proportions and melt forms a flammable substance (known as caramel or caramel) with a melting point of 400 ° C, the temperature reaches 600 ° C and produces a lot of smoke.01:321080p 329 01:32Combustion of potassium nitrate and coal - KNO3 1080p

Put a long thread on an ice cube (preferably in the middle of the cube), so as to protrude from the jar. Sprinkle some salt on the ice cube, at the point where it touches the thread. Wait two minutes and try to pick up the puzzle on a string. Salt caused the ice began to melt, and then because of the surrounding cold water, frozen again, this time with the thread. The salt causes the ice to melt. Therefore, in the winter, poured salt on the roads, to remove the glaze.01:02720p 95 01:02DIY - how does the thread can stick to ice cubes? 720p

Pen ink consists of several ingredients. One of them is a dye which imparts color to the ink. When we add a drop of ink into the cold water, the ink is mixed with it by means of diffusion - dispersion of particles of ink ingredients in the water. The warm water diffusion occurs faster because the particles have more energy, and the spaces between them are larger (more easily with each other squeeze).

Mysteriously and ridiculously entitled experiment will be revealed soon. This is simply the oxidation of the molten candy gel-oxidant - potassium chlorate. The present experiment is potentially dangerous! Potassium chlorate is a strong oxidizer and sensitive, the smallest indiscretion can cause a fire.
