Answer
See the answer below.
Work Step by Step
a) < 7, strong Ka for HSO4-
b) < 7, ammonium donates hydrogen to water
c) = 7, perchlorate is a very weak base
d) > 7, carbonate is a moderately strong base
e) > 7, sulfide is a very strong base
f) = 7, nitrate is a very weak base
g) > 7, hydrogen phosphate is stronger as a base than as an acid
h) = 7, bromide is a very weak base
i) < 7, $FeCl_3+6\ H_2O\leftrightarrow Fe(OH)_3+3\ H_3O^++3\ Cl^-$
Highest pH: E, sulfide is the strongest base
Lowest pH: A, hydrogen sulfate is the strongest acid
