Chemistry Lab 1211Thursday/ 12:00pm| 2009| | Brian Longoria/Ally Orr/ Paige Reece/Michael Smith | | | investigate 29 -------Hydro metallurgy to Analyze a Chromite S adenosine monophosphatele (A Self-Directed Experiment) * purpose:To avow the presence of the components of Chromite- conjure, 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, resoluteness & 4 M Sodium hydroxide dissolve agent * Zinc metal * MeasureNet® spectrophotometer and cuvettes * Normal lab glasswork and equipment * INTODUCTION Chromite is the lonesome(prenominal) mineral ore of chromium. Chromium has various uses including the production of guiltless steel, enhancement of nonferrous alloys , hardenability and the adjustments of these alloys to be more re sistant to corrosion and oxidation. Chromium has some other more familiar everyday uses including: the plating in metals, pigments, trounce processing, catalysts, surface treatments, and refaractories. The most common form of chromite is the obscure squeeze magnesium chromium oxide.

However, in some samples, magnesium hindquarters 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 tonus of the process is extracting the metal. Extraction is the proc ess of removing metal from ore by dissolving! the metal in a suitable solvent, whence acquire the metal from the solution, and discarding licentiousness 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 substance or...If you want to get a full essay, read it on our website: OrderEssay.net
