Problem
Consider the following species at 25 °C:
• NH3, Kb=1.8×10−5
• ClO−, conjugate base of HClO where Ka(HClO) = 3.2\times10^{-8}
• C6H5NH2 (aniline), conjugate base of C6H5NH3+ where Ka(C6H5NH3+) = 2.5\times10^{-5}
Rank the three species NH3, ClO−, and C6H5NH2 in order of decreasing basic strength in aqueous solution. Present your answer in the form “strongest base > … > weakest base.”
