dissolving carbon dioxide into water produces a weak acid called carbonic
acid. This is what is produced when raindrops fall through the atmosphere;
they absorb CO2 as they go, and if they land on limestone they slowly
dissolve it. coke cannot be alkaline, so cannot neutralize an acid. however
a weak acid solution CAN be used to further dilute a stronger acid solution
(though battery acid is pretty dilute too).
