Steel will corrode as the iron in it is more reactive than copper.
Since all 1975 nickels are made from a combination of copper & nickel, I would have to see a picture of your coin to see what you're talking about. You can send it to Working.Man@usa.net

Yes, copper sulfate is an electrolyte.
Usually in a school experiment, you put copper solution into glass. Then you add Positively and negatively charged sticks which are connected with each other and plugged into electricity, which makes pure copper form on the negatively charged stick.
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
The solid copper is a conductor but not an electrolyte.

Copper itself is one of the elements. It contains nothing but copper. It might be alloyed with nickel sometimes, but that would not always be the case.You may be thinking of the fact that nickel was sometimes found mixed in with copper ore. Its hardness compared to that of copper caused such problems for miners in Saxony that they called it "Kupfernickel", a German word that translates roughly as "Devil's copper". Eventually the "Kupfer" prefix was dropped, giving us the word we use today.

erm....nickel Not quite ... US nickels are actually made from an alloy of only 25% nickel, the rest is copper. Canadian nickels were once pure nickel, but in recent years they've been made of steel because the price of nickel rose to the point where the amount needed would cost more than five cents. Copper. The mix is 75% copper and 25% nickel.
