Does limestone float on water?
No, it sinks. That is an absolute answer for an ideal piece of Limestone and pure water. However in day to day life we we can observe limestone floating on warter if a) limestone is porous with air trapped in it , and/or b) water is not pure containing heavier substances dissolved in it like salts etc. +++ Limestone is not that porous! In fact most limestone is barely porous at all. It is correct that solid objects are more buoyant in brine or similar aqueous solutions more dense than pure water, but the difference is by no means enough to make a piece of rock float.

What effect does carbonic acid have on limestone?
Limestone is one of a few minerals to seriously be effected by sulfurous acids. Decrease in weight and structure from the release of magnesium salts is well noted. Yellowing will first be noted while release and accumulation of salts takes longer. Over time, temperature and moisture cause structural weakening as the limestone becomes pocked and porous from the chemical destruction.
