The effect of different concentrations of Iron (III) Chloride with the mass loss of copper. The aim of my investigation is to study the effect of the rate at which copper is fixed by different concentrations of Iron (III) Chloride. I will place copper strips in varying concentrations of Iron (III) Chloride, and then record results and interpret them. The reaction above is used in technology. Printed Circuit Boards are thin, flat boards made from non-conduction materials eg.plastic. Chips and other components are mounted on to them. The PCB starts off as a sheet of plastic coated with a layer of copper. It is placed into a tank containing a concentrated solution of Iron (III) Chloride to remove the excess copper and the protected copper, which remains become the PCB tracks. This is the formulae of the reaction which takes place between copper and Fe3+ ions shown below: Cu (s) + 2Fe3+ (aq)...
