Tartrate
I made some potassium tartrate. It is easy to make because it very soluble. The flask remained few drops solution so I added some nickel chloride to
make nickel tartrate. Nickel tartrate is green. Later I will make more nickel tartrate and other tartrates. This is few drops mixture photo. But why
my potassium tartrate solution yellow? What impurity make it so yellow?

Lots of things are yellow. There’s no way to answer that without more information. What did you make your potassium tartrate from, and where did the
chemicals come from?

I used KOH and tartaric acid. I some years ago buyed them in a chemical supplies shop. potassium tartrate very soluble, many days also didn't
crystalise, but sodium tartrate not so soluble, it very easy crystalise out. I tryed heat potassium tartrate solution but it still don't crystalise,
added isopropyl alcohol also no use. I also made copper tartarate, it is blue, but it has 2 types, 1 type is lighter blue, other 1 type is bluer, I
don't know need how to separate them. in the piture that 2 layers are I say that 2 types.

If you want to purify your tartrate, add another equivalent of tartaric acid to you potassium tartrate. Potassium hydrogen tartrate is fairly
insoluble, and crystallizes nicely.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Method:
mix metal salt solution (NiCl2, CuSO4) and potassium tartrate solution, metal tartrate precipitate out.
