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) Electrolysis is often used to electroplate metal objects. Sketch an electrolysis cell used to silver plate a metal spoon...

Name: Electrochemistry and Equivalent Mass Figure 4: Electrolysis of NaCl(a) "brine" solution. 4. Refer to figure 4, an illustration of the electrolysis of a NaCl(aq) solution, called a brine". This method is used to manufacture chlorine gas and sodium hydroxide. Chlorine is widely used to purify water, as a disinfectant, and in the making of important compounds such as chloroform, a compound used in the production of Teflon. Chloride ions are oxidized in the anode half-cell and water is reduced...
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...
