on that basis H2SO4 shud also not be an acid as it also has only OH groups
the final acidity also depend on the extent to which -OH group can be ionised
if it can be easily ionised................it is a strong acid

H3BO3 can accept a pair of electrons
it is a monobasic lewis acid
it is weakly acidic
it can accept a pair of electrons from OH-
to form
B(OH)4-
