How Much Copper Is in the Coin?
We calibrated three different molarities of copper (II) nitrate. We tested for the %Transmittance of 1M, 0. 1M, and 0. 01M and plotted the data collected on a calibration curve based on concentration and absorbance. We used nitric acid to dissolve a penny to produce another copper (II) nitrate to test its %Transmittance and plot that on the graph to discover the concentration of that […]
