Starter: Iron presence in the human body

Why is Iron present in the human body?



While one BlurIt user stated that Iron is needed in the human body for some reason to do with becoming an Iron man, another has given the reason to be directly related to the presence of haemoglobin which largely consists of Iron as a mineral and is quite important for the circulation of Oxygen throughout the body (As it seems that iron has an ability to enjoin the Dioxygen atoms).

How to test for Iron Deficiency (Anemia)?



Iron deficiency, known as Anemia, can be tested for via several methods, differing by the physical case, of which, the most prime is a complete blood test in which a blood sample is taken, and the amount of red cells in a certain volume is compared in ratio with the amount of white blood cells in the same volume, and then related to a default standard known to be “healthy beyond doubt”. This can also apply on other blood content, such as Transferrin proteins which are responsible of containing the iron in the haemoglobin. Other Anemia tests include, but are not limited to Ferritin tests examining the amount of iron in the body as a whole, Lead level test examinating lead toxicity which is a main cause of Anemia in children and Bilirubin tests examining if the red blood cells are being destroyed within the body which may be a sign of hemolytic anemia.

What is the relation between Titration and Anemia examinations?


Titration can also be used for the purpose of examining Anemia: You can find the concentration of iron(II) ions in solution by titrating with either potassium Manganate(VII) solution or potassium dichromate(VI) solution. The reactions are done in the presence of dilute sulphuric acid.

What is Titration and what are its uses?


Titration as I find it is a funny word, which refers to the chemical laboratorial process of examining the amount of reactant solution needed to complete a reaction with a second solution. This is most commonly known in the process of neutralisation, where a certain amount of Base can be added onto Acid until they are completely neutral (With the use of some nifty-coloured indicators!)
