Quantitative Analysis: % Copper in an Ore

May 3, 2006

Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis, we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass.

Introduction: Chemical analysis takes place under two different scenarios. In one case, you need to find out the chemical identity of some material. The first kind of analysis, in which the chemical nature of a sample is determined in the lab0 or in the field, is called qualitative analysis. In the second type of analysis, the analyst, in which amounts of specific substances are measured, is quantitative analysis. As in this experiment is to determine the mass percentage of copper in a copper ore sample, using a variety of analytical methods.
