Iron
Discovered : known to ancient civilisations.
Origin : The name comes from the Anglo-Saxon ‘iren’, and the symbol from the Latin ‘ferrum’, meaning iron.
Description :Iron is an enigma - it rusts easily and yet is the most important of all metals, world production exceeds 700 million tons a year. Small amounts of carbon are added to iron to produce steel and when chromium.
is added to this, the result is non-corroding stainless steel (small amounts of nickel may also be added). Iron is also an essential element for all forms of life. The average human contains about 4 grams, much of which circulates as haemoglobin in the blood, the job of which is to carry oxygen from our lungs to where it is needed. If the diet does not contain 10 milligrams a day, anaemia will eventually develop. Foods such as liver, kidney, molasses, brewer’s yeast, cocoa and liquorice contain a lot of iron.

Can water burn?
It’s known that water consists of atoms of molecules of oxygen and hydrogen. Since any compound with oxygen indicates the ability of the substance to burn, water is no exception. Thus, water has a surprising property of already "burnt out" compound.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
