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....

Re: Colloidal gold
We dont give recommendations for food, pharmaceutical products.
We dont discuss to make this kind of things, because we dont know what impact it has to human body. It's a chemical forum and no medicinic forum.

Re: HELP, Bifenthrin in a chemical equation??
Lead is poison. Need good ventilation or fume hood.
Next time please open a new thread. The topic in the head line has nothing to do with lead.

Some reduced products of the citrate.
Mainly aconitic acid and Isocrotonic acid salts

Re: Colloidal gold
Yes gold will be oxidised to Au 3+ by chloride
The citrate is reducer back to gold.
There several methods in the net.

Re: Colloidal gold
To less information. Where does the Gold comes from. With salt, citrate and corn syrub you cannot make Gold.
Which movie do you refer to.

Re: PhD application
I would ask the universities requirement. But degrees mostly not so important to get things done. Later in a job nobody ask for it.

Re: HCl Concentration
HCl is a gas. The acid is a solution of this gas. With boiling is not possible. The gas has to be pressure into the solution.
But did read what I said before. NaCl acetic acid will not react. You have still a mixture of salt and vinegar.
