ElectroChemica 002

The experiment illustrated below is a replication of one of the electrochemical sedimentation experiments, mentioned in a previous blog entry.
I chose to carry out the experiment on water colour paper, with the intention of capturing a residual trace of the process.. Two copper electrodes were used in a solution of Ferrous Sulphate, the centre (cathode) being connected to the negative terminal of the 20v power supply and the outer ring (anode) to the positive. The images below were taken over approximately 2 minute intervals.
