No, it is not poisonous, in fact it's added to many foods.

Okay, let's take the basics: There is no such thing as "copper sulfate baking powder", as it would be poisonous. I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
Barium is not poisonous in the form of its sulfate. That's because barium sulfate is insoluble in water. Unless a barium compound dissolves with the subsequent release of barium ions, it is not going to be highly toxic.
sulfuric acid. Dilute sulfuric acid will react with both lead and ferrous nitrate when dissolved in water producing-: nitric acid, ferrous and lead sulfate. Ferrous sulfate is very soluble in water and lead sulfate is only slightly soluble and so the lead sulfate should pretty much precipitate out of the solution. This method will not completely separate the lead from the iron; however, Its a start. And also you can keep boiling down the solution of the 2 salts until pretty much most of the lead sulfate is separated from the iron sulfate. But if it were me , because of the poisonous nature of lead compounds, I would not want to use this as a source of iron.
i think either potassium(II) sulfate or potassium sulfate
Copper sulfate is not a metal There are two compounds called Copper Sulfate, which are salts of the metal Copper. CuSO4 is Copper (II) Sulfate, once known as Cupric Sulfate. Cu2SO4 is Copper (I) Sulfate, once known as Cuprous Sulfate.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.

Barium sulfate is used as a contrast agent in some medical imaging. It is insoluble in water, so it sort of drifts through the gastrointestinal tract. This irritates the tissues, but doesn't act as an outright poison as barium ions (which are poisonous) are not released into solution.
sulfate. SO4 Sulfate. SO4
copper sulfate, cupric sulfate, cupric sulphate.l
Iron(II) sulfate. Or the older formula name, Ferrous sulfate.
