A salt of each of the ions in Table is dissolvedin water. A Pt electrode is immersed in each solution and con-nected to a 0.38-V battery. All of the electrolytic cells are run forthe same amount of time with the same current.(a) In which cell(s) will a metal plate out? Explain.(b) Which cell will plate out the least mass of metal? Explain.
(c)Ions that react with Ag+ like SCN- can be determined electrogravimetricallyby deposition on a silver working anode:Ag(s) + SCN- ≤ AgSCN(s) + eA silver anode with initial mass of 12.4730 g was used to electrolyse 85.00 mL of asolution of 0.0245 M KSCN. At the end of the experiment, the anode weighed12.5767 g. How long did the experiment take, if a current of 100 mA was used?
A cell consisting of a saturated calomel electrode and a lead ion electrode developed a potential of -0.3257 V when immersed in a 60.00 mL lead solution of unknown concentration. A 10.00 mL addition of 0.02500 M lead standard solution caused the reduction potential to shift to -.2897 V. Calculate the molar concentration (in units mM) of lead in the sample. Please make sure to perform necessary calculations to have a final answer in mM.
(a) A Cr3+(aq) solution is electrolyzed, using a current of7.60 A. What mass of Cr(s) is plated out after 2.00 days?(b) What amperage is required to plate out 0.250 mol Crfrom a Cr3+ solution in a period of 8.00 h?
