Agree with all you've said, except for the "H2CO3 powder" part. Ain't
no such animal. H2CO3 is impossible to get in a pure state at normal
temperatures. I'd be surprised if it had been done even cryogencially.
CO2 disolved in water is 99% molecular disolved CO2 gas, and 1% H2CO3
(in an equilibrium state). It's just about impossible to raise the
H2CO3 content higher than that.
