I'm not so sure exactly what happened to them - I was doing a project on electrolytes, and I was using a multimeter for measurements of current and resistanceI put the probes in a solution of table salt and water, and I had two pieces of aluminum foil on either side of the plastic container the solution was in (these sheets of foil were serving as conductors, so I could figure out the resistivity of the solution)I had two copper wires connected to either terminal on a 6V batteryWhen I connected the copper wires to the aluminum foil, the solution started fizzing at the edgesI put the probes in and took some readingsWhen I pulled them out, the probe nearest to the conductor connected to the negative terminal had a copperish looking coating on it, along with some black coatingAlso, the foil connected to the positive terminal had disappeared, like something ate at it (it had holes in it)I'm pretty sure this was a type of chemical reaction; any ideas on how to reverse/fix it?
