Procedure The goal of the investigation was to conduct an analysis to determine the composition of an ore sample. The mining companies needed to know if there was enough copper in the ore to make it worth mining. The first step was to develop a method to determine the concentration of a copper(II) ion solution. Our group was given an ore sample, acid, and a device to measure light absorbance. Using the acid, the copper(II)-nitrate compound

Unformatted text preview: was dissolved to produce a blue solution. The solution was put into a spectrometer. Several different solutions were created with varying amounts of ore and acid. Absorbance data for each concentration was collected and a graph was constructed. The graph was useful in determining the copper concentration in unknown ore samples....
