Lithium - a bit of chemistry series Traditional Cache

This cache has been archived.

Darick: Ran into a cacher at the CITO event this morning who reminded me that I needed to check on this one, so I swung by on my way home. The place was crawling with soccer muggles, but I found a place to park and walked over to ground zero, only to find the hiding place for the cache missing! I'm going to let this one go...

Geocache Description:

Quick park and grab in Papillion City Park and sports complex. You can park just a few feet from ground zero. If there is a soccer game or practice going on, muggles will be an issue... 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. Someone was throwing out a whole sack of these containers. I'm not sure how it will stand up to the elements, but I thought I would do some experimenting. By submerging the container underwater for several minutes, I proved it was waterproof... as long as the lid is replaced tightly, so please do that. The second part of the experiment is putting some out in the wild... we'll see how they do.

************************* LITHIUM *************************

Lithium

Atomic Number: 3

Symbol: Li

Atomic Weight: 6.941

Discovery: 1817, Arfvedson (Sweden)

Word Origin Greek: lithos, stone

Properties: Lithium has a melting point of 180.54°C, boiling point of 1342°C, specific gravity of 0.534 (20°C), and valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements. It has the highest specific heat of any solid element. Metallic lithium is silvery in appearance. It reacts with water, but not as vigorously as does sodium. Lithium imparts a crimson color to flame, although the metal itself burns a bright white. Lithium is corrosive and requires special handling. Elemental lithium is extremely flammable.

Uses: Lithium is used in heat transfer applications. It is used as an alloying agent, in synthesizing organic compounds, and is added to glasses and ceramics. Its high electrochemical potential makes it useful for battery anodes. Lithium chloride and lithium bromide are highly hygroscopic, so are used as drying agents. Lithium stearate is used as a high-temperature lubricant. Lithium has medical applications, as well.

Sources: Lithium does not occur free in nature. It is found in small amounts in practically all igneous rocks and in the waters of mineral springs. The minerals that contain lithium include lepidolite, petalite, amblygonite, and spodumene. Lithium metal is produced electrolytically from the fused chloride.
