Okay, a few more questions here...
Cu + S2O8-2 ——> CuSO4 + SO4-2
In this notation, I'm guessing the S2
can represent ammonium persulfate, plus others like Sodium and Potassium sulfates? Also, where does the ammonium ion fit in on the right hand side of the equation?
Since these are anhydrous crystals being mixed with water, should I treat the ammonium persulfate as a hydrate?
Also, the brochure on my ammonium persulfate says the solution is non-reusable due to "out gassing." I'm assuming this is a release of ammonia gas?
Finally, if the solution gets contaminated with a small amount of NaOH, would sodium sulfate be one of the products?
