The empieric formula is 30 g/mol, but the measured molar mass was 60 g/l.
It could be also 180 g/mol if it is a sugar C6H12O6 means 6 x CH2O.
Empieric formula says nothing about the real molecule. Only with 30 g/mol it could be formaldehyde.

Re: Condition of disharge sulfat anions on anode
If you want to obtain the metal, then a aqueous solution is sufficient. The sulfat will not be attacked. Its common way to do electrolysis. If you melt a chloride you get chlorine by electrolysis. But where do you get the hydrogen. This happens only also in an aqueous solution or you have to produce...

Re: Condition of disharge sulfat anions on anode
Ammoniumsalts will decompose to ammonia and hydrogen. The anion reacts like above to peroxodissulfate.

Re: Chemistry
You cannot deposit copperoxide by electrolysis. This is only possible with copper itself.

Re: Chemistry
You cannot make Cu2O solution, because it is not soluble. If you create it, it will precipitate imidiatelly. Probably can make nano particles or spray version. Maybe Fehling solution could be used. https://en.m.wikipedia.org/wiki/Fehling%27s_solution Your solution can be made dissolve coppersulfat a...

Re: Condition of disharge sulfat anions on anode
Conc. sulfuric acid has an conductivity of 1,044 · 10−2 S/cm.
It has an autoprotolysis like water
2 H2SO4 => H3SO4+ + HSO4-
A sulfate salt enhance because more HSO4- is produced
H2SO4 + Na2SO4 => 2 NaHSO4

Re: Condition of disharge sulfat anions on anode
Water free sulfuric acid is like a melted sulfate. Alkalisulfates will stop at Peroxodisulfate, iron, chromium and others decompose to sulfuroxides.

Re: Condition of disharge sulfat anions on anode
Sulfate of Sulfuric acid will convert to peroxodisulfate, further to disulfate and sulfurtrioxide.
2 SO4 2-=> S2O8 2- + 2 e-
2 S2O8 2- => 2 S2O7 2- + O2
S2O7 2- => SO4 2- + SO3
2 SO4 2-=> S2O8 2- + 2 e-
2 S2O8 2- => 2 S2O7 2- + O2
S2O7 2- => SO4 2- + SO3

Re: Condition of disharge sulfat anions on anode
No In diluted sulfuric acid or solution of sulfate salts, SO4 2- will be not discharged, instead of Oxygen will be developed. 2 H2O + 2 SO4 2- => 2 H2SO4 + O2 + 4e- In molten alkalisulfates peroxodisulfate will be created. Technical method to produce persulfates 2 SO4 2- => S2O8 + 2 e- https://en.m....
