I doubt it would absorb that much carbon dioxide if it were to just sit there, especially if it is in a relatively tall/narrow jar. There's not very much surface area, and the lack of agitation should help too.
If cholrine evaporates, does any microbacterial matter start to "bloom" ?
IIRC there isn't really much in the way of chlorine in your water by the time it gets to your tap. The chlorination step is done at the plant, and then I believe they try to remove as much chlorine as possible. Tap water probably doesn't have enough nutrients to support microbes anyway. If you added some flour though you could make yourself a nice sourdough starter!
Are airborn pathogens more likely to disolve in water sitting ?
Dunno. Like I said before, there isn't that much surface area exposed to the air, so it probably wouldn't be significantly different than fresh tap water unless you had pathogens pumped directly into the water.
What benefit would you expect the vessel or just sitting to bring to the water ?
I'm not sure about that one. For one thing, it would allow particulates to settle.
If you ever want to scare yourself, take a gallon of florida tap water and let it sit for a week.
What happens? I'm actually kind of curious, because that could dash my somewhat-educated guesses to pieces.
