Zinc Sulfate and Acetone
In battery,
I take the surrounded metal (I think it's pure Zinc metal) and stick somewhat Manganese dioxide on it
I put Zinc into Sulfuric Acid ~4M to get Zinc Sulfate solution
Next I pour Acetone to this solution and I get precipitate
but I don't know what it is
By the way, In Ethanol, I pour it into Copper Sulfate solution and Potassium Nitrate solution (rate about 1:1) by syringe (not slowly)
Similarly, I get precipitate and dry it
But in Copper Sulfate, the precipitate has quite blue color and softer
Anyone plz explain it for me
Thanks

Most probably this is just the zinc sulfate you wanted, as it's insoluble in acetone or acetone-water mixtures.
EDIT: Ethanol has the same effect, as it greatly decreases the solubility of salts in water when poured into it. With copper sulfate, this just may be
the hydrate of the salt. As you described, it is blue and softer than potassium nitrate, which precipitates out without forming a hydrate.
