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?
