electrolysis

One important use of electrolysis is to produce hydrogen. In the future, this could play a central role in shifting our society over to a reliance on hydrogen as an energy carrier for powering electric motors and internal combustion engines. (See hydrogen economy.) Electrolysis of water can be achieved in a simple hands-on project, where electricity from a battery is run into a cup of water. Hydrogen gas will be seen to bubble up at one of the immersed battery probes, and oxygen will bubble at the other. The energy efficiency o ...

Chlorine (from the Greek language Chloros, meaning "pale green"), is the chemical element with atomic number 17 and symbol Cl. It is a halogen, found in the periodic table in group 17. As the chloride ion, which is part of common salt and other compounds, it is abundant in nature and necessary to most forms of life, including the human body. As chlorine gas, it is greenish yellow, is two and one half times as heavy as air, has an intensely disagreeable suffocating odor, and is exceedingly poisonous. In its liquid and sol ...

Cold fusion is the name for a claimed nuclear fusion reaction that would occur well below the temperature required for thermonuclear reactions (millions of degrees Celsius) in a relatively small "table top" experiment utilizing electrolytic cells. The idea was first brought into popular consciousness by the Fleischmann-Pons experiment in March of 1989, which was front-page news for some time. The subject has been of scientific interest since nuclear fusion was first understood. Hot nuclear fusion using deuterium yields large am ...

Waxing is a temporary method of hair removal which removes the hair at the root. New hairs do not grow back in the waxed area for up to three to eight weeks. Almost any area of the body can be waxed, including eyebrows, face, bikini area, legs, arms, back, abdomen and feet. Waxing is accomplished by spreading a wax combination thinly over the skin. A cloth or paper strip is pressed on the top and then ripped off with a quick movement against the direction of hair growth. This removes the wax along with the hair ...

Chemical decomposition or analysis is the fragmentation of a chemical compound into elements or smaller compounds. It is sometimes defined as the opposite of a synthesis. A generalized reaction formula is: AB → A + B. An example of analysis is the electrolysis of water 2H2O → 2H2 + O2. Another recognized form of decomposition is hydrogen peroxide. If you keep it for a long time, the hydrogen peroxide will eventually decompose into water and oxygen: 2H ...

Christian Friedrich Schönbein (October 18, 1799 – August 29, 1868) was a German-Swiss chemist who is most well-known for his discovery of guncotton. He also discovered ozone, a form of oxygen, in 1840 during the slow oxidation of white phosphorus and the electrolysis of water. Although his wife had forbidden him to do so, he occasionally experimented at home in the kitchen; one day in 1845, when his wife was away, he spilled a mixture of nitric acid and sulfuric acid. After using his wife's cotton apron to mop it up, he hung ...

A unibrow, or monobrow, is the presence of abundant hair between the eyebrows, so that the eyebrows seem to join up above the nose to form one long eyebrow. In Western culture, the unibrow is often derided as being a throwback to a "primitive" state or as exhibiting a lack of self-grooming. Hence, especially among women, the region between the brows is often plucked or treated with electrolysis or other forms of depilation. Unibrow separation is often the only form of eyebrow grooming (a stereotypically feminine behavior) among men. However, in some countries t ...

An anode (from the Greek άνοδος = 'going up') is the electrode in a device that electrons flow out of to return to the circuit. Literally, the path through which the electrons ascend out of an electrolyte solution. The other charged electrode in the same cell or device is the cathode. For electrons to flow through the anode a positive charge is applied to the anode (attracting electrons). Anode - Flow of electrons. The flow of electrons is always from anode–to–cathode < ...

A cathode is the electrode at which electrons go into a cell, tube or diode whether driven externally or internally. It comes from the Greek word κάθοδος meaning, 'going down'. The other charged electrode in the same cell or device is the anode. Cathode - Flow of electrons. The flow of electrons is always from anode–to–cathode outside of the cell or device and from cathode–to–anode inside the cell or device regardless of th ...

An ionic compound is dissolved with an appropriate solvent, or otherwise melted by heat, so that its ions are available in the liquid. An electrical current is applied between a pair of metal electrodes immersed in the liquid. The negatively charged electrode is called the cathode, and the positively charged one the anode. Each electrode attracts ions which are of the opposite charge. Therefore, positively charged ions (called cations) move towards the cathode, while negatively charged ions (termed anions) move toward the anode. The energy r ...

As well as producing hydrogen, electrolysis also produces oxygen. Nuclear submarines are able to generate breathing oxygen from the water around them. This enables submarines to stay underwater for an indefinite period of time. Space Stations can also use electrolysis to produce extra oxygen from waste water or surplus water produced from the Space Shuttle fuel cells. Both these applications depend on having an abundant electrical supply, either f ...

Although electrolysis occurs in pure water, it is a very poor conductor of electricity. It is necessary to add a water-soluble electrolyte, the ions of which are harder to oxidize or reduce than water. Ions flow through the solution, thereby completing the electric circuit. 2 H2O + 2e− → H2 + 2 OH− E0red= −0.83 V 2 H2O → O2 + 4H^{See also:}
