heres a gas pressure vessel can i get some advice.
TimFox:
I use Google and Wikipedia to find quickly a treatment that others can look at.
I have lots of textbooks from my student days, but they are hard to cite.
Not looking anywhere at all, even in "quaint and curious volumes of forgotten lore" when dealing with chemistry and other obscure topics, is not useful.

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?

This is correct. The dissolved solids come back if you evaporate the water (but as the bicarbonate, not the carbonate). The CO2 will not fume off unless you make it very hot.

This is correct.
--- Quote ---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!!

Wikipedia has its faults, but is is mostly correct about most things.

--- End quote ---
This is not correct. Hydrogen gas, like oxygen gas, is neutral. If you dissolve it in water it does not change the pH.

I'm yet to see the litmus test on it!!!

--- Quote ---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.

Gawd, this is so far off any basic understanding of chemistry as to be beyond the pale.
Well, as suggested earlier, livestream the procedures, eventually you will get to a teaching moment.
LaserSteve:
OK< Link is incredibly disturbing and gross.
This is what happens when things go wrong with oxidizers and pressure vessels:

His parents permitted the use of the pictures in the safety film. May he rest in Peace.
I still wonder if OP is trolling us.
If you have no clue what your doing, it is time to leave this experiment alone.
