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

Re: Molecular formula of the compound CH₂O
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.
