Ammonum persulfate react with brass.
Hydrogen peroxide will work.
Magnesium persulfate
Digest (dissolve) a small portion of the brass in nitric acid. Then test the sample for copper content using an atomic emission or atomic absorption spectrometer.
The Answers to this Question is Brass in a solid form, air in a gas form, and Aqueous in a liquid form.
Usually when the 3 elements aren't involved at a deeper emotional level ( no chemistry), so to speak. The connection is dissolved.Hope that answers your inquiry. Just Kidding!
Yes it will dissolve liberating H2 gas.
Ammonium sulfate is (NH4)2SO4 and ammonium persulfate is (NH4)2S2O8. Ammonium persulfate is an oxidizing agent.
The chemical formula of copper(II) persulfate is CuS2O8.
K2so5
Li2S2O8
Only the spelling: persulfate is the US spelling, persulphate is the UK spelling. They are both the same chemical.
Hydrogen peroxide will work.
It will dissolve brass slowly. It can be used as cleaner, but it results in a reddish color. Rinse the brass parts with H2O2 may get back the original color, too much and it will turn greenish.
Etching copper circuit boards.
it releases sulfur dioxide and oxygen?
Formula: Ni2(S2O8)3
Ammonium chloride is thermally decomposed in ammonia and hydrogen chloride.
