Chemistry: acids and bases? (need a smart chemistry person)?

Question

What are the three species that actually exist in significant amounts in a one-tenth molar aqueous solution of HCl?

Explain why hydrogen ion (H+) is NOT one of the three species.

Answer 1

Water, of course, chloride ions, and H3O+ ions.

H3O+ is sometimes written as H+(aq), but don't let that mislead you. Real H+ would be a naked proton, which is much too electron-attracting to exist free in any environment except an ionised gas.
