Question
Part A 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 What mass of Cu(s) is electroplated by running 17.5 A of current through a Cu2(aq) solution for 4.00 h? metal plated depends on the number of electrons passed. The total charge of a mole of electrons is 96,485 coulombs (C) and Express your answer to three significant figures and include the appropriate units. 1 ampere (A) =1 coulomb/second (C/s) Templates Symbols uado redo reset keyboard shortcuts help, Value Units Submit Request Answer Part B How many minutes will it take to electroplate 22.1 g of gold by running 5.00 A of current through a solution of AuT(aq)?
