Product description
5. Two 200 cm3 measuring flasks were filled with 10 cm3 of wastewater. One flask was filled with 10 cm3 of a standard solution with a copper titer of 0.00065 g/cm3. The necessary reagents were added to both flasks, and the volumes were brought up to the mark. When photometrically measuring the solutions, the optical densities obtained were 0.29 and 0.35, respectively. Determine the concentration (g/l) of copper in the wastewater.
