Electrochemistry

Electrochemistry Imagine that we have an object that is made of copper or steel, and that it has been properly cleaned, and that we now want to plate it with nickel. A wire is attached to the object, and the other end of the wire is attached to the negative pole of a battery (the wire is blue in this picture). To the positive pole of the battery we connect the red wire; the other end of the red wire we connect to a rod made of nickel. Now we fill the cell with a solution of a salt of the metal to be plated. It is theoretically possible to use a molten salt, and in rare cases that is done, but most of the time the salt is simply dissolved in water. The NiCl2 ionizes in water to Ni++ and two parts of Cl- Because the object to be plated is negatively charged, it nickel, ni, wire, object, charged, solution, salt, plated, metal, electrons, chloride, because, water, red, recommend, possible, positively, pole, now, negatively, made, end, connect, cell, been, battery, attached, anode, two, time, thus, theoretically, supplying, steel, state, simply
