Two acids, P and Q, which have equal concentration and equal volume, are each reacted separately with an equal mass of magnesium ribbon. Both reactions give the same final volume of hydrogen gas, but acid Q reacts much more slowly than acid P. Which explanation for the difference between P and Q is correct?
- AAcid P has a higher pH than acid Q.
- BAcid P has a lower concentration of hydrogen ions.
- CAcid Q is partially dissociated and acid P is fully dissociated.
- DAcid Q is a proton acceptor.
