Chemistry Lab 1211Thursday/ 12:00pm| 2009| | Brian Longoria/Ally Orr/ Paige Reece/Michael Smith | | | try out 29 -------Hydro metallurgy to Analyze a Chromite S adenosine monophosphatele (A Self-Directed Experiment) * employment:To avow the presence of the components of Chromite- weight-lift, Magnesium, and atomic number 24- in an aqueous beginning in put in to identify and unknown sample of ore. * MATERIALS: * Iron (III) nitrate, solid & Chromium (III) nitrate, solid * 1.00 M Hydrochloric acid, ascendant & 4 M Sodium hydroxide resolution * Zinc metal * MeasureNet® spectrophotometer and cuvettes * Normal lab glasswork and equipment * INTODUCTION Chromite is the wholly mineral ore of chromium. Chromium has various uses including the production of guiltless steel, sweetener of nonferrous alloys , hardenability and the adjustments of these alloys to be more resistant to corrosion a nd oxidation. Chromium has some other more familiar everyday uses including: the plating in metals, pigments, leather processing, catalysts, surface treatments, and refaractories. The most common form of chromite is the obscure put right magnesium chromium oxide.

However, in some samples, magnesium drop veer for iron, and aluminum and ferric ions can substitute for chromium (Experiment 29379). A procedure that utilizes aqueous solution interpersonal chemistry for the recovery of metals from salts, minerals, or ores by extractive metallurgy is known hydrometallurgy. The source timber of the process is extracting the metal. Extraction is the process of removing metal from o re by dissolution the metal in a suitable so! lvent, whence recovering the metal from the solution, and discarding overplus materials; operations to perform extraction includes take (dissolving by water or acid), which is common with additive agents; separating the waste and purifying the leach solution; and precipitating the metal or one of its pure compounds from the leach solution by chemical or...If you want to get a full essay, read it on our website: OrderEssay.net
