What is a strong acid?

1 Answer

A compound with a proton #"H"^(+)# that is easily dissociated (removed) into solution. Another way of looking at this is by considering the pH. A pH < 3-4 at #25^@ "C"# is considered strongly acidic.


Generally a compound that loses a proton #"H"^(+)# in an acid-base reaction which forms a weak (stable) conjugate base in turn is considered a strong acid.
