... by electricity is known as electrolysis and the copper gained on the cathode is known as the electrolyte. From this, it would seem logical to assume that the greater the amount of electricity, the greater the amount of copper that will move from the anode to the cathode. It would seem easy enough to measure the mass of copper that has moved to the cathode, but what is the 'quantity of electricity.' In both the 'Hutchinson' and 'Collins' science dictionaries (Michael Upshell and D. McMonagle respectively), electricity is described as a ' flow of charges in a current.' However on the CD-ROM Electrochemistry (New Media), more depth and detail is found. It states electricity is a flow of electrons, and since electrons are negatively charged particles, electricity must be the flow of the charge.' When copper is deposited on the cathode, the equation is: Cu2+ + 2e- ? Cu (s) This equation ...
