Sulfur - a bit of chemistry series Traditional Cache

This cache has been archived.

Darick: A bit of a failed experiment here... have replaced this one many times, but it keeps coming up for maintenance. Have tried several ways of keeping this in place, but no luck. Time to let it go.

Geocache Description:

Quick park and grab near Schwer Park. Parking is available (N41° 10.124 W096° 3.291) 150 feet from ground zero. Muggles might be walking by, in the parking lot, driving on the street, or in nearby houses... so be aware of who may be watching before making the grab. Bring your own pen/pencil.

This is part of a series of caches all using the same container. The experiment continues... first, the container was proven to be waterproof as long as you replace the lid tightly (please do). Second, they seem to be holding up in the elements, at least for the short term. Next experiment is internal log construction... trying a more secure method of attaching the log to the lid to ensure quick and simple log extraction and to reduce maintenance issues. Let me know if you have any comments/annoyances with these containers.

************************* SULFUR *************************

Atomic Number: 16

Symbol: S

Discovery: Known since prehistoric time.

Word Origin: Sanskrit: sulvere, Latin: sulpur, sulphurium: words for sulfur or brimstone

Properties: Sulfur has a melting point of 112.8°C (rhombic) or 119.0°C (monoclinic), boiling point of 444.674°C, specific gravity of 2.07 (rhombic) or 1.957 (monoclinic) at 20°C, with a valence of 2, 4, or 6. Sulfur is a pale yellow, brittle, odorless solid. It is insoluble in water, but soluble in carbon disulfide. Multiple allotropes of sulfur are known.

Uses: Sulfur is a component of gunpowder. It is used in the vulcanization of rubber. Sulfur has applications as a fungicide, fumigant, and in the making of fertilizers. It is used to make sulfuric acid. Sulfur is used in the making of several types of paper and as a bleaching agent. Elemental sulfur is used as an electrical insulator. The organic compounds of sulfur have many uses. Sulfur is an element that is essential for life. However, sulfur compounds can be highly toxic. For example, small amounts of hydrogen sulfide can be metabolized, but higher concentrations can quickly cause death from respiratory paralysis. Hydrogen sulfide quickly deadens the sense of smell. Sulfur dioxide is an important atmospheric pollutant.

Sources: Sulfur is found in meteorites and native in proximity to hot springs and volcanoes. It is found in many minerals, including galena, iron pyrite, sphalerite, stibnite, cinnabar, Epsom salts, gypsum, celestite, and barite. Sulfur also occurs in petroleum crude oil and natural gas. The Frasch process may be used to obtain sulfur commercially. In this process, heated water is forced into wells sunk into salt domes in order to melt the sulfur. The water is then brought to the surface.
