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 bear be given a one gram prototype of Chromite. Chromite is delimitate as an Iron Magnesium Chromium Oxide. The tar mystify 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 discernn sample is in truth 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 post to do so, the experimenter has a confine list of chemicals to use, which complicate: * Iron (III) Nitrate, Solid * Chromium (III) Nitrate, Solid * 1.

00 M Hydrochloric hellish solvent * 4 M Sodium Hydroxide Solution * Zinc Metal The experimenter in any case has price of admission to unlimited use of: * Standard lab equipment and glassware * MeasureNet temperature investigate * MeasureNet pH probe and drop counter * MeasureNet spectrophotometer and Curvettes In this experiment, the experimenter ordain utilize different skills learned from previous labs in magnitude to conduct the experiment in a productive and businesslike manner. For instance, Chemical reactions will be utilized in order to separate the conflate unknown sample into its various components. unity must know tha t the driving force behind reprise displace! ment reactions is the removal of ions, and one must also know that a hurry reaction is used when two sedimentary solutions of ionic compounds are mixed, and a solid is formed. Another manikin of students using knowledge from a previous experiment is when the experimenter must perform an electric arc analysis on the rest aqueous Chromium solution. One last bit of consequential information to have is that some(prenominal) metals have the property of...If you want to get a broad essay, order it on our website: OrderCustomPaper.com
