Making Copper Nitrate

[Matthew]

I was wondering if there is any way to make copper nitrate with potassium nitrate and copper sulfate? Nitrates are more reactive than sulfates and copper less reactive than potassium so would the reaction from CuNO₃ and KSO₄? If so is there any way to separate the chemicals? They both appear to be soluble.

But to do what with the copper nitrate? It's almost impossible to dry it and even harder to keep dry. Like ammonium nitrate, pretty useless for pyro.

You could always just buy it . . .

Mixing them wont really do much. You might be able to extract off copper nitrate with alcohol. I think I tried this once, but without a ton of success or great yields. The reaction works better if you use something that precipitates as an insoluble sulfate. Calcium nitrate is the cheapest source usually. It can be a little difficult to remove all the calcium though if you care about color.
