To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A ), which expresses the amount of charge, in coulombs (C ), that flows per second (s ): 1 A=1 C/s Another unit of charge is the faraday (F ), which is equal to a mole of electrons and...

Part A and B
Please show all of the steps
Analysis of Electroplating When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is...

Part E
Please show all of the steps
Introduction to the Nernst Equation Learning Goal: To learn how to use the Nernst equation. The standard reduction potentials listed in any reference table are only valid at standard-state conditions of 25 C and 1 M. To calculate the cell potential at non-standard-state conditions, one uses the Nernst equation, E – E – 2.303 RT log.Q where E is the potential in volts, E is the standard potential in volts, R =...

Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...

Review Constants 1 Periodic Table Part A Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au' solution. The item itself serves as the cathode, at which the Au't ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit. What...
