Electrolysis

Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze…

The book “BAD SCIENCE” is really a book that provides great information about the facts which are hidden from people in normal circumstances. People tend to believe in their superficial advantages of various products marketed by companies or individuals who prefer their monetary interests over public interests. They use every possible way to create a target market for their products by giving baseless scientific justification about the effectiveness of their new inventions. I am of the view that…

Forensic chemistry is the application of chemistry to provide information for use in courts of law or in public discussion and debate. It is a special branch of chemistry that is concerned with identifying the substances present in samples. A forensic chemist analyses predominantly biological samples such as blood, saliva, and semen (of which all contain DNA, proteins and amino acids) that are brought in from the crime scenes and reaches a conclusion based on tests run on that piece of evidence.…

containing the agarose gel. Such equipment would avoid the cross-contamination that usually occurs when using traditional electrophoresis equipment. Additionally, this advancement has proven that pH change and bubble formations will not occur, as the electrolysis of water (decomposition of water due to an electric current) will be reduced. This is because conductive polymers are able to be oxidized and reduce themselves (eureka). This new method of electrophoresis is said to provide more…

them less common. In terms of transportation, electric cars require charging which takes longer than refueling and is unavailable in most convenient locations. Hydrogen cells are less efficient than gas-powered vehicles as they require either the electrolysis of water or the separation of hydrogen and carbon from hydrocarbons. Both these processes for the creation of hydrogen result in the use of energy that must be produced by other methods, resulting in an energy source less efficient than the…

Many options are available today for people looking for alternatives to traditional methods of healthcare. Most people are not aware of the different approaches to health and healing that can be taken. The term alternative medicine is, “used simply to denote approaches to health and healing that do not rely on drugs, surgery, and/ or other conventional medical procedures for treating illness.” (Goldberg). When becoming involved in alternative medicine, a world of possibilities is introduced.…

surface. Hair regrowth shows no reduction in the amount of hair or any changes to the appearance of the hair. Electrolysis - This technique uses a thin metal needle to get to the base of the hair follicle, where it's zapped with an electric current. This effectively cauterizes the hair follicle and prevents future hair growth. Laser hair removal is the common alternative to electrolysis for permanent hair removal. In this method, a concentrated beam of light is aimed at hair. The light is…

In electrolytic chlorination (i.e., electrolysis), an electrical current is directly applied to seawater generating free chlorine, sodium hypochlorite and hydroxyl radicals. During the electrolytic chlorination process, a certain salinity level in ballast water is required or additional salt…

Mr Jose Pool Chemistry Equilibrium system and stress factors Jake 14/08/2014 Pool Chemistry Introduction Pools with crystal clear water look inviting on a hot day however there may be unseen hazards. Invisible dangerous pathogens and microorganisms may be present in pools that aren’t treated properly and can result in harmful side effects like swimmers ear or diarrhoea. Disinfectants are used to treat pools and chlorine is by far the most commonly used. Hypochlorous acid (HOCl) is the…

Mission To Mars “We choose to go to the moon, not because it is easy, but because it is hard” -John F Kennedy. Back in May of 1961, John F Kennedy challenged the United States to land a man on the moon, and be the first to do it. However, now the challenge has escalated from a moon landing to a landing on an entirely different planet… and living there. Many different organizations have proposed the idea and are currently working on figuring out if we can reach Mars. We have to ask ourselves, how…
