N02), a 2 ohm 10 W resistor, five female AC plugs, chassis mount (for the mechanical pumps, diffusion pump heater, CuO tube heater, etc.), five tineon lamps, 125 V, 0.3 W, five SPST 10 A power switches, a fuse holder, an amphenol 5 pin hex chassis mount female connector (to receive male connector with wires from alligator clips attached to leads on Toepler pump), a 6 foot power cord,... 

Furthermore, the electrode should always be immersed carefully into the electrolyte solution. Otherwise, corrosion products of the electrode body or of electrode connectors are almost guaranteed to spoil the intended electrochemical experiment. Corrosion will preferably occur at loci of high current densities, which are typically produced when contacts to the electrode made by alligator clips are immersed into the electrolyte solution. This is also true for the case where entire solid samples need to be contacted in order to undertake electrochemical studies. Therefore, under no circumstances should the contact area be allowed to be wetted by the electrolyte solution. This problem can be circumvented by suitably covering the contact area in the case of an electrolyte solution with low surface tension, this process can be hard work and may even lead to the construction of a special cell design. 

Potential measurements of metal in soil require the use of some assistance tools, such as insulated wire, reels, alligator clips, terminal connectors, hand tools, a reference electrode (RE), 2ind specialized equipment like voltmeters and ammeters. 

Before beginning the experiments, a few procedural things have to be covered. The source of electricity will be a 9 volt battery, and the connections will be made through clip leads. (The latter word is pronounced "leed," not "led" like lead metal would be.) In supply catalogs, the clip leads are sometimes described by other phrases such as "test leads," "jumper cables," or "patch cords." Because of their appearance, the adjustable connectors at the ends are called "alligator clips."...
