Re: Complex Formation Equilibria
You need the complex building constant for CeY-.
Ce 3+ + Y 4- => CeY-
K = CeY-/(Ce 3+ *Y 4-)
pH dependency

K = CeY-/(Ce 3+ *Y 4-)

Re: K3RhCl6
I would react the salt first with sulfuric acid, to get rid of the Chloride.
The remaining Rhodiumsulfate can be electrolysed. Cathode what ever you like. Anode carbon preferred.

Re: K3RhCl6
You can try electrolysis or reduction with strong reducer, like SnCl2 or v
Ascorbic acid.

Re: Redox reactions and standard electrode potentials
All compounds who has lower potential as - 0.029V will work as reducer, what means triiodide will work as oxidiser in this case.
No, it is opposit. 0V is more positive as - 0.029Vie, in combination with hydrogen, the triiodide ion will be a reducing agent...). Am I right?

Re: Biochemical properties of piruvic acid
You mixed it up. A physician is a doctor for medicine. What you mean is a physisit, who work with physics
So we don't give recomandation for medicine or application, and also not for making bombs or other pyro stuff, like molotov, etc.
Its forbidden to post here.

Re: Biochemical properties of piruvic acid
Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or converted to fatty acids through a reaction with acetyl-CoA. It can also be used to construct the amino acid alanine and can be converted into ethanol or lactic acid vi...

Re: How to calculate values through graphs
Al2(SO4)3 + 3 Ba(OH)2 => 3 BaSO4 + 2 Al(OH)3 2 AlCl3 + 3 Ba(OH)2 => 3 BaCl2 + 2 Al(OH)3 Aluminiumsulfate will give a precipitate of BaSO4 and Aluminiumhydroxid, Aluminiumchlorid will only give a precipitate of Aluminiumhydroxide. In the first equation correspond x Ba(OH)2 to x *2/3 Al(OH)3 and to x ...

Re: How to make Sodium hydroxymethanesulfonate
You mix equimolar amount of bisulfite powder and formaldehyde. Let it crystallize under a good ventilated hood.
NaHSO3 + CH2O => HOCH2- SO3 Na
It can be produced also as byproduct from Dithionite

Re: Condition of disharge sulfat anions on anode
No I am in Europe.
I have no idea what products you get in your device.
Maybe you have to do tests and experiments.
One concern is the water free sulfuric acid. It is very hygroscopic and will absorb water from the humidity in the air.

Re: Condition of disharge sulfat anions on anode
You mean SO3? Sulfur trioxide, Sulfuric anhydride ?
Probably yes. Normal sulfate will convert to disulfate, trisulfate,etc.
SO4 2- + SO3 => S2O7 2-
S2O7 2- + SO3 => S3O10 2-
And so one gets ( SO4 * n SO3) 2- , this should be conductive
