Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
Chemical tank / container / vessel. While economic considerations are a factor, the design of chemical storage containers and how the chemistry may impact the environment is crucial. Chemical tank A chemical tank-vessel is of necessity designed for a specific chemical, as all chemicals have variable corrosion potentials there are no, one size fits all. The chemical and application parameters should design tank-vessel, the following is a "tip of the iceberg" view of what goes into defining a Chemical storage tank. A. The Chemical tank represents the first line of control for aggressive chemicals. The primary control of the chemical, consists of
