heres a gas pressure vessel can i get some advice.

Yes you are right, I'm not the most wisest chemist at all,  All I know is salt disappears in water for some unknown mystery and it all snowballed from there.

If you add co2 to water you get a rise in ph, and its linear to pressure.  (and a change in ph will increase crystalization.) It makes carbonous acid.  (On the internet it calls it carbonic acid,  but it isn't.    sulphurous acid is when sulphur dioxide is added to water, and it "softens" gypsum.)

I don't know for sure,  But I figure if you add oxygen it lowers ph.   they are both gasses,   so I guess all gasses do it.  I may be wrong.

Carbonous acid (with CO2) "softens" carbonate minerals.
Sulphurous acid (with SO2) "softens" sulphate minerals.  (like Gypsum.)

So If Sulphur and Carbon do it,  I'm guessing oxygen does it as well, but I'm also guessing it softens it even more! because its more potent a gas.

Then the gas pressure has a briquetting action on the softened mineral.  (I put it in a special collapsing mould, that allows a few millimetre's of shrinkage.)  So it softens it, then it pushes it together in a scintering type action, both with the same mechanism, compressed gas.

Thats the idea,  I told you its quite simple and primitive.    I know!!! it happens with sulphur dioxide and carbon dioxide, but its only weak, yes, But with oxygen it may be stronger at the same pressure, but its a mystery I have to try to find out.

Its a stab in the dark of a generalization,  might be true,  might not,   have to find out.

It dissolves. It will come back again if you evaporate the water.

It makes carbonic acid. The internet is correct. Carbonous acid is another name for formic acid, which is something else entirely.

I don't know what you mean by "softens". Gypsum is a mineral. It is hard. Nothing "softens" it.

Oxygen does not lower pH, because oxygen is neutral.

All gases are different, so different gases do different things. You cannot generalize like that.

Carbonic acid can dissolve carbonates like limestone. It doesn't soften them. They remain hard until they dissolve, and then they are gone.

Sulphur and carbon are solids. Oxygen is a gas.

"More potent a gas" does not mean anything in this context.

Not sure what you are trying to say here.

There is no softening. That is not a thing.

KaneTW:
Just... shut up. Stop. Don't do this, or anything related to chemistry, or elevated pressures, or electricity for that matter, until you have a firm grasp of the basics.

TimFox:
Generalizations about chemistry usually require looking at the Periodic Table.
Oxygen and carbon are in different columns.  Sulfur is under oxygen, but sulfur dioxide is different from molecular oxygen.
Does dissolved oxygen affect pH?  Once again, Google gives us this result:  https://atlas-scientific.com/blog/does-dissolved-oxygen-affect-ph/
I suggest that you do some simple research before asserting: "I don't know for sure,  But I figure if you add oxygen it lowers ph.   they are both gasses,   so I guess all gasses do it.  I may be wrong"
When I was young, I read a bad translation of Verne's "20,000 Leagues Under the Sea" that kept referring to "carbonic acid" when it meant gaseous CO2 in the local atmosphere, which confused me since I had just read a children's book about medical disinfectant and thought it meant "carbolic acid", a quite different chemical.

They come back just like salt does, at the bottom of the pot when the acids all fumed off. (Into co2 :) )  If they just "disappear and not come back" Where did they go to?

Its how to make a salt,  with a metal and an acid.     And chalk is another kind of salt.


Seems funny, but I dont trust wikipedia for anything much at all,  I find other sources way better.
But like I said, I could be wrong about this whole thing, I dont mind if I am.    I'm just prooving things myself cause I trust bugger all around me!!


You might be able to inject hydrogen into water as well, and it goes acidic.   (but I think oxygen stops it turning into a hydroxide. but I could be wrong easily.)
