Initially, into the atmosphere. Water molecules, exposed in the 
atmosphere to solar radiation, break down over time. Some of the 
hydrogen escapes off planet. The remaining hydrogen and oxygen combine 
with other elements to create acidic compounds.

This is what's thought to have happened to the oceans of Venus. On that 
planet, the main compound in question is H2SO4. In the atmosphere of 
Earth, there's less Sulphur and more Nitrogen. I guess that would make 
the most likely candidate HNO3.

I'm no expert and this is a worst-case. It's probably only slightly more 
likely than the rose-coloured view that God's in His heaven and all's 
right with the world. Even so, is the risk worth taking?
