Rust Removal by Electrolysis

1) The visible "outer-layer rust" is a powdery or scaly reddish-brown or reddish-yellow substance called Hydrated Ferric Oxide, or Hydrated Iron (III) Oxide, with a chemical formula Fe2O3 (nH2O) During the process of rusting, the outer-layer rust undergoes a large increase in its volume; as a result, the rust cracks and flakes off, thus ....

Experiment 3

If a second extraction is needed, the layer to be extracted is placed in the Sep Funnel and a new portion of the extracting liquid is added, and the shaking, venting, process is repeated This is commonly encountered during the "work up" of a chemical reaction, when the organic layer is washed with several different aqueous solutions...

Extraction

The upper phase should not be drained through the stopcock - this would contaminate it with material from the lower phase which may adhere to this part of the glassware Obviously, if further extraction of the lower phase is required, it can be added to the empty sep funnel, fresh upper phase added, and the extraction operation carried out...

Iron Sulfide

Pyrite oxidation begins with the oxidation of sulfur by oxygen yielding sulfate, ferrous iron, and acidity The rate-limiting step is the oxidation of Fe 2+ to Fe 3+, which occurs only very slowly at low pH chemically, but is catalyzed by bacteria that speed up the reaction rate by a factor of 100 000Once underway, the process of pyrite oxidation may continue until the source is exhausted...
