September 12, 2023Solubility of copper sulfate complex in acetic acid
Both plain copper sulfate and your copper ammonia sulfate complex are a lot more soluble in water than copper acetate. So you are quite right that your precipitate is copper acetate. If you add acetic acid slowly enough to the copper ammonia sulfate solution, you should see a colour change from deep purple to blue before the precipitate forms. This is because to begin with, some of the acetic acid will react with the ammonia, protonating it to form NH*4*+ ions, which cannot bind to the copper. As more acetic acid is added, the copper precipitates as Cu(OAc)2 solid. Excess acetic acid will drag this back into solution by forming the Cu(OAc)*3*- complex ion, which looks like this .

May 7, 2014Why is the answer D and not C? Copper(II) sulfate is soluble in water so won't be found in a powder, no?
Copper(II) sulfate must have been present in the powder for it to dissolve. The question is asking what was in the powder before water was added. More on reddit.com

September 1, 2023Why do Hydrated Copper (II) Sulfate crystals not dissolve from the water or crystallisation?
In rough terms, because there is not enough water for that. The hydrate is a pentahydrate salt IIRC. It is just the right amount of water to exist in the solid phase, lodged in between the ions. More on reddit.com

I am trying to solve a problem and I think I did but don't have solutions to check it. Here is the problem:
The solubility of anhydrous copper(II) sulfate at 100 C is 4.72 mol/kg. How much copper(II) sulfate pentahydrate can be obtained from 306 g of such a saturated solution?
I got that 206 g of copper(II) sulfate pentahydrate can be obtained. Could someone check, please?
