Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis, metals and gases may form at the electrodes. …To understand electrolysis, you need to know what an ionic substance is. Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. For example, sodium chloride forms when sodium reacts with chlorine. It contains positively charged sodium ions and negatively charged chloride ions. Ionic substances can be broken down by electricity. … For electrolysis to work, the ions must be free to move. Ions are free to move when an ionic substance is dissolved in water or molten(melted). For example, if electricity is passed through copper chloride solution, the copper chloride is broken down to form copper metal and chlorine gas. … Here is what happens during electrolysis : Positively charged ions move to the negative electrode during electrolysis. They receive electrons and are reduced. Negatively charged ions move to the positive electrode during electrolysis. They lose electrons and are oxidised. … So the electrolysis of copper chloride solution produces copper at the negative electrode. But the electrolysis of sodium chloride solution produces hydrogen.  2, record 2, English, - copper%2Dchloride%20electrolysis

Protective lead aprons and thyroid shields contain lead to shield the wearer from radiation. Lead aprons and thyroid shields are placed between the person being protected and the x-ray source (for example, radiographic or fluoroscopic x-ray units, CT scanners, DEXA scanners). X rays are more likely to interact with large atoms (atoms with lots of protons and electrons) than they are with smaller atoms, and lead, tungsten, and even gold are examples of large atoms that can be used. Each time an x ray interacts, it uses some or all of its energy to knock electrons in the atoms around. When all of the energy is used up interacting with atoms, the x ray ceases to exist.  2, record 8, English, - protective%20apron

Chlorine induced corrosion is the most important corrosion process in power plants, firing waste, coal and/or biomass. Depending on the process, chlorine is present as HCl gas, as solid KCl and NaCl in ashes or as eutectic melts i.e. KCl-ZnCl₂ in deposits of waste fired boilers. In the presence of HCl gas and solid chlorides, "active oxidation" is generally accepted as the major corrosion mechanism. Metal chlorides are formed by inward diffusion of chlorine to the metal/oxide interface, evaporating and subsequently oxidized to non-protective oxides and additional chlorine.  4, record 11, English, - metallic%20chloride

... many workers favour the idea of metal transport in chloride complexes.... Barnes & Czamanske(1967) have argued with reference to ZnS that bisulphide complexing is important and chloride complexing relatively insignificant. Helgeson(1964) contended that chloride complexing increases sphalerite solubility in chloride solutions when sulphur is low, whereas Barnes(1976b) has proposed that transportation as chloride complexes requires a solution to be virtually sulphur-free.  1, record 19, English, - chloride%20complexing

Zoning... cannot be used to distinguish between the products of these two types of solution, because chloride complexing up to at least 100°C is not sufficiently strong to change significantly the normal order of precipitation of sulphides from that found for simple metallic ions. It does not appear... that the nature of the zoning in hydrothermal deposits points to deposition from sulphide complexes, and that chloride complexes or ionic solutions may play a significant role as metal transporting agents in the formation of sedimentary sulphide deposits.  1, record 19, English, - chloride%20complexing

Nitrates have been implicated in the cracking of wires made of nickel brass alloy that are used in telephone equipment, but no other evidence exists for metal corrosion. Since nitrate salts are more hygroscopic than chloride or sulphate salts, nitrates may lower the threshold requirements for wet metal corrosion.  1, record 22, English, - wet%20metal%20corrosion
