![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.
