Help! How to make up ferrous sulfate solution
First thank you very much for reading my message. I am fully appreciative of those who respond to my question. I want to set up a tank with nickel sulfate plating solution. This solution will be used to plate on copper material. Those who worked with solution before, please advise me what we need to set up the tank and how to make up a solution. My questions are: what chemical compositions pH range and what chemical used to adjust pH What type of anode How to avoid chemical solution from oxidation Any more information will be very much appreciated I have some information from Metal Finishing Book but it is not enough. I like more information from those who actually had worked with this solution.
PS: We want to use Ferrous Fluoborate solution but since there aren't company product this solution any more; therefore, we are trying different solution such as Ferrous sulfate instead.

What do you want to know about, nickel plating or ferrous sulfate? One has nothing to do with the other. If you get a little (lot?) more specific, maybe we can give you some direction.

Thank for replying. I meant ferrous sulfate. Sorry for a mistake.

Hi, Hanh. Iron plating baths like these are not widely used; that's probably why you are having trouble locating a supplier. Iron plating is important in soldering iron manufacturing but not much else these days :-)
As mentioned in letter 37918, Lowenheim's "Electroplating" offers six formulations for iron plating baths. The simplest is probably the 240 g/l FeSO4.6H2O bath operated at ph 2.8-3.5 and temperature of 32-65 deg. C, current density 400-1000 A/sq. m. (You must avoid air agitation to keep from oxidizing the dissolved iron).
letter 37918 also offers, a reader's suggestion for a simple bath. Good luck.
