Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. CuSO4From the stock solution (0.040 M), pipet 0.00, 2.00, 5.00, 10.00, 15.00 and 20.00 aliquots into 100 mL volumetric flasks. Develop the color (royal blue) by adding enough NH3 solution to form Cu(NH3)42+ complex. Add 10 mL excess to stabilize to complex. Dilute to the desired volume. Determine the concentration of each standard solution and tabulate. *I'm not sure if a Dilution Factor (DF) is still needed in here but I hope you can also explain this if DF is still needed in the computation.
