Compare complete and partial acid ionisation, hydrogen-ion concentration, pH and reaction rates while separating acid strength from concentration.
Two acids, P and Q, with the same concentration and volume are reacted separately with the same mass of magnesium ribbon.
The reactions produce the same total 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?
Acid P has a higher pH than acid Q.
Acid P has a lower concentration of hydrogen ions.
Acid Q is partially dissociated and acid P is fully dissociated.
Acid Q is a proton acceptor.
