1. Your question is ambiguous. Do you want to grow large nickel sulphate crystals, or do you want to make nickel sulphate from other chemicals? If
the latter, what do you want to use as a source of nickel?
2. Don't ask for answers via E-mail. This is a discussion board, not a helpline. Answers given to your questions could potentially be of use
to other people. There is no valid reason why you should be the sole beneficiary of replies.
3. When asking very basic questions, post them in the Beginnings forum.
4. Proof read your posts. A typo in the subject title is hardly encouraging.

There was a time when I was trying to obtain nickel salts. I dissolved Ni in HCl/H2O2 and boiled down till some NiCl2 hydrate precipitated out. But
it was going slow so I gave up for a bit. Looking up solubilites I found that nickel sulfate is somewhat less soluble so I decided to precipitate out
my nickel as the sulfate with sulfuric acid. I would add some acid and get a precipitate and add more and get a precipitate but I forgot that the HCl
thus generated came out in corpious amounts and nearly overcame me. When I was done I had a large volume of fluffy white precipitate. I let it set
for a few days and the volume of precipiate had decreased and I decanted. A few more days and the volume had once again decreased and I decanted
finally when I reached the very bottom the precipitate was no longer fluffy (about 2 weeks) instead large crystals jutted up from the bottom and all
the fluffyness had gone, it all fuesed together. Very interesting.
