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 extend be given a one gram sample distribution of Chromite. Chromite is delimitate as an Iron Magnesium Chromium Oxide. The tar issue forth 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 agnizen sample is really 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 localize to do so, the experimenter has a confine list of chemicals to use, which take on: * Iron (III) Nitrate, Solid * Chromium (III) Nitrate, Solid * 1.

00 M Hydrochloric sharp-worded firmness * 4 M Sodium Hydroxide Solution * Zinc Metal The experimenter in any case has irritate to unlimited use of: * Standard lab equipment and glassware * MeasureNet temperature try * MeasureNet pH probe and drop counter * MeasureNet spectrophotometer and Curvettes In this experiment, the experimenter impart utilize different skills learned from previous labs in nine to conduct the experiment in a productive and cost-effective manner. For instance, Chemical reactions will be utilized in order to separate the conflate unknown sample into its various components. ace mustiness know that the driving force behind retell displa! cement 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 example 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 of the essence(predicate) 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
