Uga Chem Lab Exp 29

Alex Evans Sanders Dellinger Ryan Shockney Rashaad Williams October 18, 2010 Experiment 29 Procedure Proposal In this prove, the experimenter submit be given a one gram test of Chromite. Chromite is delimitate as an Iron Magnesium Chromium Oxide. The clinical of this lab is for the experimenter to determine if Iron, Magnesium, and Chromium atomic number 18 in the un make outn sample, and from these conclusions, realize if the un enjoyn sample is truly Chromite. In doing this, multiple science lab skills are needed, along with general intimacy on the elements comprised in the experiment to be covered. As aforementioned, the main objective of this lab is to determine whether or not the unknown sample is in fact chromium. In graze to do so, the experimenter has a confine list of chemicals to use, which admit: * Iron (III) Nitrate, Solid * Chromium (III) Nitrate, Solid * 1.00 M Hydrochloric ill-natured resolving power * 4 M Sodium Hydr oxide Solution * Zinc Metal The experimenter in any case has assenting to unlimited use of: * Standard lab equipment and glassware * MeasureNet temperature dig into * MeasureNet pH probe and drop counter * MeasureNet spectrophotometer and Curvettes In this experiment, the experimenter allow for utilize different skills learned from previous labs in assure to conduct the experiment in a productive and streamlined manner. For instance, Chemical reactions will be utilized in order to separate the conflate unknown sample into its various components. tincture of iodine must(prenominal) know that the driving force behind biramous displacement reactions is the removal of ions, and one must also know that a hurry reaction is used when two aqueous solutions of ionic compounds are mixed, and a solid is formed. Another role model of students using knowledge from a previous experiment is when the experimenter must perform an electric arc analysis on th e be aqueous Chromium solution. One last bi! t of great information to have is that some(prenominal) metals have the property of...If you want to draw and quarter a broad essay, order it on our website: OrderCustomPaper.com
