What combination of substances will give a buffered solution that has a pH of 5.05? (Assume each pair of substances is dissolved in 5.0 L of water.) (Kb for NH3 = 1.8 × 10–5; Kb for C5H5N = 1.7 × 10–9)

◦ 1.0 mole NH3 and 1.5 mole NH4Cl
◦ 1.5 mole NH3 and 1.0 mole NH4Cl
◦ 1.0 mole C5H5N and 1.5 mole C5H5NHCl
◦ 1.5 mole C5H5N and 1.0 mole C5H5NHCl
◦ None of these are correct.
