Hi Mike, you cant get the metal into solution that way. You can get Nickel metal from a solution by displacement, and you could get Nickel Chloride to displace with copper sulphate. But from what i gather from the thread, the debate was how best to plate nickel onto iron.To get nickel into solution, can't you do a displacement reaction with good old copper sulphate? Or, maybe copper chloride!
This threads almost 9 years old and sat nearly dead for a good part of it so I am pretty sure there is no need to hurry on your part.Maybe then I can explain a half decent theory for you. I cant do much for a few days,
that's what i was thinking, a replacement reaction could work. nickel is almost as reactive as iron. for electroplating though, i wonder if the sulphate or nitrate would be safer. any way you slice it, you will have some gases liberated during plating. when i was a kid, i used to electroplate pennies with iron using a very crude setup. one thing i learned with electroplating was it's a process that likes lots of current. higher current means: a) more metal plates out in a given amount of time, and b) larger surface area requires more current. you want the connection to the cathode to be up out of the solution. you want the anode to be made of the metal you are plating. for a power supply, all that's really needed is a transformer and rectifier. you won't have much control of the current, unless the supply is on a variac. you may want to use a regulated bench supply with an adjustable current limit, so that you can regulate the current. spacing between the anode and cathode will also have an effect on the current. if the workpiece needs to be double sided, use two anodes one on each side. quite often i would get a workpiece that was plated on one side, and not much plating on the other side.To get nickel into solution, can't you do a displacement reaction with good old copper sulphate?
