Chemistry experiments is the king when it comes to scientific experiments absolutely amazing, here will show ten simple and wonderful chemical experiments, make a great science as well.
Copper and nitric acid
When copper acid mode with nitric acid, is formed with us a green solution and then brown to green italic, and if we mix the solution with water, water is displacing nitrates from all over the copper and the solution changes to blue.
Hydrogen peroxide with potassium iodide
This chemical experiment known as the teeth of the elephant toothpaste, one of the dramatic performances interesting. The interaction between hydrogen peroxide and potassium iodide releases a large amount of foam, and if we add food coloring we can make it similar to the planned toothpaste. We can also add yeast instead of potassium iodide, where foam is produced but more slowly.
Sugar drying
One of the simplest and most beautiful experiments occurs when sugar is mixed with sulfuric acid, where sugar is heavily dried. The result is a column of black carbon, heat fumes, and a strong smell of burning caramel.
Experience barking the dog
Dog bark is the name that is called the chemical reaction to the production of light, and occurs via an exothermic reaction (absolute heat) between nitric oxide or nitrogen oxide with carbon dioxide. When igniting the mixture in a tube produces a bright blue light accompanied by a distinctive bark or can be compared with the voice of the dog. All you need in the experiment is a tube and alcohol.
Hot ice
Hot ice is the name given to sodium acetate, and sodium acetate is a chemical produced by the reaction of vinegar and baking soda (sodium carbonate). The sodium acetate solution is able to cool rapidly so that it can crystallize and when the crystals are formed we get the heat. All you want in the experiment is water and salt.
Making an electric tree
There are several ways in which you can make an electric tree. These trees are named after the objects of Schistenberg in relation to the German physicist Georg Christoph Lichtenberg. Electrical trees are formed by discharging electrical charges in an insulator.
We can through the use of polyethylene and talc powder, and there is an easier way by using a sharp metal object, an insulator (eg acrylic sheet), ink.
Making polymer rebars
All of us may know rubber balls, or what was sometimes called in colloquial language. The rubber balls were originally made of natural rubber and then made of plastic and other chemicals.
The materials you need to make fake balls are: borax (used in detergents), corn starch, white glue, warm water, food coloring .
Flame Coloring
We can easily color the flame and make amazing offers like a colorful rainbow of flame. We only use chemicals that give every color in addition to fuel, which is alcohol, for example, which gives blue, strontium nitrate or lithium salt.
Calcium chloride gives orange color, sodium chloride (table salt) gives yellow color, boric acid (insect killer) gives green color, potassium chloride gives violet color.
Thermite reaction
The reaction of the thermite shows what happens if the iron rusts immediately, instead of rusting over time, in other words it makes the iron burn, and if the conditions are correct, any metal will burn. However, interaction is usually performed by reacting iron oxide with aluminum. (Eg when the meat is iron)
Alkaline minerals in water
Any alkaline minerals will react strongly in water, for example sodium burns and shows bright yellow flame, potassium burns and shows a violet flame. Lithium burns and shows flame in red, cesium explodes.
It is known that sodium is an unstable alkaline metal and needs to abandon one electron to become stable. When a small piece of water is placed in the water, a strong chemical reaction occurs and produces sodium hydroxide and hydrogen gas
