B-15 13. Silver plating occurs when electrolysis of a Ag2SO4 solution is used because silver metal is formed at the (cathode/anode). This is the (+/-)electrode. The reaction at this electrode is: Recall that 1 A=1 C/s and 96,500 Coulombs = 1 mole is (Faraday's constant). Also, 1 V=1 J/C If a cell is run for 200. seconds with a current of 0.250 amps, how many grams of Agº will be deposited? Standard reduction potential of silver is 0.80 V. How many joules of energy is needed? 14. A current of 10.0 amperes flows for 2.00 hours through an electrolytic cell containing a molten salt of metal X. This results in the decomposition of 0.250 mole of metal X at the cathode. The oxidation state of X in the molten salt is (X+, X2+, X3+, X4+) 15. Solutions of Ag+, Cu2+, Fe3+ and Ti++ are electrolyzed with a constant current until 0.10 mol of metal is deposited. Which will require the greatest length of time?
