The Cr plating on a surface that measured 3.00 4.00 cm was dissolved in HCl. The pH was suitably adjusted, following which 15.00 mL
The Cr plating on a surface that measured 3.00 × 4.00 cm was dissolved in HCl. The pH was suitably adjusted, following which 15.00 mL of 0.01768 M EDTA were introduced. The excess reagent required a 4.30-mL back-titration with 0.008120 M Cu2+. Calculate the average weight of Cr on each square centimeter of surface.
