Copper plating was accomplished using either graphite or copper as the electrodes. How would you expect the copper(II) ion concentration of the solution change (i.e. would [Cu2] increase, decrease, or remain the same?) during the plating process if the graphite anode were replaced with a copper one in the electrolysis of CuBr2? Explain your answer 5. Calculate the mass and thickness in mm of the chromium plate on an object if a current of 450.0 mamps were allowed to flow...

C2 T14HW Question 17 Homework . Unanswered Fill in the Blanks How long would it take to plate 5.00 grams of iron if a current of 5.18 A is passed through an Fe(NO3)2 solution? time = hrs
Q6. The electrolysis of BiO+ produced pure bismuth (Bi). How long would it take to produce 10.0 g of Bi by the electrolysis of a BiO+ solution using a current of 25.0 A?
Q2. Copper ores rich in ultra-soluble sulfate minerals are leached using water. Finely grounded solid copper ore with 1000 kg/h, contains 20% CuSO4 (copper sulfate) and 70 % insoluble solids (Feed, F). The rest 10 % is contaminants and ignore their existence in your calculations. (Take only copper sulfate (solute) and solid content of the Feed.) The leaching occurs in a two- stage, counter-current system using 3000 kg/h of water as pure solvent. The ratio of kg insoluble solid to...
