Solutions of thiosulphate breakdown into sulfur, sulfites and sulfates when exposed to acids, light, metal ions
Dear Evelyn,
Sulfur belongs to the chalcogen family. Other members of the family are oxygen, selenium, tellurium, and polonium. The periodic table is a chart that shows how chemical elements are related to each other. sulfur sometimes occurs in bright yellow layers on the top of the earth. It has a sharp, offensive odor. The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation. They are a particular type of plasma lamp, The sulfur lamp consists of a golf ball-sized (30 mm) fused-quartz bulb containing several milligrams of sulfur powder and argon gas at the end of a thin glass spindle. The bulb is enclosed in a microwave-resonant wire-mesh cage. A magnetron much like the ones in home microwave ovens, bombards the bulb, via a waveguide , with 2.45 GHzmicrowaves. The microwave energy excites the gas to five atmospheres pressure, which in turn heats the sulfur to an extreme degree forming a brightly glowing plasma capable of illuminating a large area. Because the bulb heats considerably, it is necessary to provide forced air cooling to prevent it from melting. The bulb is usually placed at the focus of a parabolic reflector to direct all the light in one direction.
