Electrolysis is often used to electroplate metal objects. Sketch an electrolysis cell used to silver plate a metal spoon in an aqueous solution of silver cyanide, Ag(CN2. Label anode, cathode, direction of electron flow, and write the cathode half-reaction. Calculate the time required to plate 0.100 g of silver on a metal spoon using a current of 500 mA. (3 marks)

what is electrolysis and what is the overall reaction in this
experiment? write out the half reactions occurring at each
electrode (assuming you are electroplating copper.
Electroplating is the process by which a thin layer of metal is deposited on an electrically conducting surface. In electroplating, the metal to be plated is used as the anode and the electrolytic solution contains an ion derived from that metal. In this experiment, the copper electrode will be used in a solution of...

In a galvanic cell, a spontaneous redox reaction occurs. However, the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o_cell = E^o_rad + E^o_ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o_ox has the opposite sign of E^o_rod. You can also write the equivalent equation...

In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...
