The table shows a series of standard additions of Cu(II)to acidified water samples measured by anodic stripping voltammetry at a platinum electrode. The unknown and all standard additions were made up to the same final volume. 1. What chemical reaction occurs during the concentration stage of the analysis? 2. What chemical reaction occurs during the stripping stage of the analysis? 3. Plot absorbance as a function of the concentration of Cu (II) standard. Determine the equation of the line and the X intercept. Find the concentration of Cu(II) in the water.
