Totally noobish question, but I was looking at a patent where they say,
e.g.1 600 parts MnSO4 in 2900 parts H2SO4 (50%)
Give me grams, moles, molar concentration, but PARTS, WTF is that meant to mean.
Help me move beyond such trivial nonsense PLS

Come on, someone help old babs here, he has some serious electrolysis to be done, and he cant start till he has this sorted, so pls someone help the
new kid on the block. 
Spoon feed this fucker, he wont shut the fuck up, and is
driving himself nuts over this issue. I also want a lolly pop, for admitting ignorance of what is likely something simple!!!!!

It may be that they don't want to tell you - patents are an interesting mix of revealing information but keeping bits of it hidden.
Or it may be that it doesn't matter.
MnSO4 is a solid; it's unlikely to have been measured out by anything other than weight.
You can weigh out the acid too.
The point of using "parts" is that it doesn't matter much what units you use.
Mixing 600 grams of MnSO4 with 2900 grams of 50% H2SO4 will give the same concentration as mixing 600 pounds of the solid into 2900 pounds of the
liquid.
It probably doesn't matter hugely if you use volumes. The bulk density of MnSO4 is probably close to that of 50% H2SO4.
Also, next time, you might want to think about waiting more than 14 minutes for someone to reply, before you get all potty mouthed about it.

I was jst messing around, and thanks for the heads up. Didn't want to waste. So yeah, much appreciated 
Im not disregarding your comment, though, cheers.

Ill scale this right down, and be mindful that they might not be all that straight. Ive heard that a fair bit. Don't trust patents completely. ITS
MINE DAMN IT, or something like that.

Would that happen to be quite an old patent, by any chance?
I think I've noticed similar vague, archaically phrased procedures myself especially when reading old stuff (like 1850-1930s)...

Electro chem for toluene --> benzaldehyde
----------------
US patent 780404
Process of Oxidizing Methyl Groups in Aromatic Hydrocarbons
Example 1:
Prepare a solution of manganese persulfate, for instance, by electrolytically oxidizing a solution of 600 parts of MnSO4x4H2O in 2900 parts of H2SO4
(about 55% sulfuric acid). This can be effected by using a lead anode and a cell furnished with a diaphragm...

Thanks, this bunny only thought this was done in a non divided cell, and include ammomium persulfate - Results positive, but yield partial. Seeing a
divided cell talk, with H2O2 utilized is interesting indeed. Thanks.
Yeah, I think it was an old patent. I just wanted the ratios. I did have a journal article, that didn't require ammonium persulfate in the mix, and
had some other uses rather than just Toluene. When found, will post. Cheers.

It's not my kind of electrochem, so I know nothing practical here. But it was easy to find, that's for sure. I prefer metals... refining and such.
Given the chance, I will read about anything in the field over newspaper headlines.
That's not to say I am awesome at it,... Never give up, never surrender
Babs - 29-7-2017 at 05:13
Yeah Im only learning this stuff. Ive used a metal as an anode, and used a graphite cathode, and in a single cell, and added say 25ml of concentrated
HCl into 350 ml or more of water, and used a 12; volt battery charger, attaching them accordingly and the metal chloride gets formed at the anode, but
its soluble, and the metal cation then travels to the cathode and finely divided parricles of metal get formed, which is pretty cool. Not in the
league of refining precious metals, but its not a race 
I
With respect to electrolysis, this is interesting.
Babs - 29-7-2017 at 05:40
I was playing around with using NiCl in order to plate the cathode with nickel, in order to use the electroplated cathode, as the sacrificial anode,
as I couldn't source pure nickel, or didn't want to pay for it. All this got interupted, but have plenty of free time now, so might have a look at
reducing some things. Of topic, and hope i haven't messed up a rule. Ill delete if thats the case.
