Hi, Rei
Well, if you want to be extremely exhaustive, yes, that is not that easy.
If you place all intermediate states and intermediate compounds, could be a nightmare for the rest.... :-(
But the fact, taking apart that is a reaction in heterogenous phase (rust is solid, and Waller's or SIO is liquid....) is that Fe3+ is reduced to Fe2+, and the solid with Fe2+ is complexed by citrate anion, that is a good chelant for Fe2+, but not enough to solubilize Fe3+ quick enough.
Anyway, yes, the extra oxygen in oxide could be used in the extra oxygen in sulfate or sulphite or used to build water...Sometimes, mechanisms looked using isotopes show that what is expected is not what is done. And in this case, I can place the equations, but I could not say from where things come....
For CO2, yes, the carbonate is releasing the CO2 when neutralizing the sulphate (and sulphite)
With best wishes

Or, the engineer's way of saying it, is -- "this stuff works."
It's kind of like the old joke illustrating the differences between scientists and engineers (btw, geologists are practical like engineers):
A scientist and an engineer agreed to take part in an experiment. They were both placed in a room and at the other end was a beautiful woman. The experimenter said every 30 seconds they would be allowed to travel half the distance between themselves and the woman.
The scientist said “This is pointless” and stormed off. The engineer agreed to go ahead with the experiment anyway.
The scientist exclaimed on his way out “don’t you see, you’ll never actually reach her?”. To which the engineer replied, “So what? Pretty soon I’ll be close enough for all practical purposes!”

Hi, GneissWare
I am by title an engineer.... Chemical engineer...
But, I am sorry, the scientist was right: never get her,,,, (maybe near enough...but never reached; and being from Jesuit formation (although feeling Buddhist...), you never know which is distance gap...Maybe too big enough....)
Being bad
With best wishes

I have to say, that joke is straying a bit close to "Your Princess Is In Another Castle" territory:
https://www.thedailybeast.com/articles/2014/05/27/your-princess-is-in-another-castle-misogyny-entitlement-and-nerds.html
(link normalized by FMF)
I know it was only meant as a joke, and I mean no offense by pointing this out. But to sum up, when was the last time you saw a joke, or a TV show, or movie, or video game, or whatnot where a guy was treated as a "prize" to some sort of challenge, but otherwise has no defining human characteristics, just the assumption that he's into whatever girl wins said challenge? Because the converse (as in this joke) of "getting a woman as a prize" is exceedingly common, and it's a dangerous motif because when we see this mirrored (often) in society, it becomes people feeling entitled to their "prize" and taking reprehensible actions when they're not "given" it.
I know this is just a joke. It's just, next time... you might consider having the inanimate, inhuman object of desire in the joke that automatically goes to the victor be an actual inanimate, inhuman obect of desire that automatically goes to the victor. Say, for example, ice cream? ;) Again, not telling you how to tell a joke, just raising an issue you might not have thought of but that matters.
(I'm not even going to touch the automatic assumption that both the engineer and scientist are men) |

Actually I think the joke works a bit better if done with a mathematician and an engineer.
Some would argue with calling both geologists and engineers practical. I know both a geologist and an engineer in the field of environmental engineering The geologist does not like to work with engineers since they seem to never have enough measurements to be satisfied. The engineer tells me there are geologists working for the firm who work on a project, plot six dots on a map an they think they are done!
Sorry, we are wondering far afield from the focus of this forum.
