Question

Determine the resulting pH when 0.040 mol of
solid NaOH is added to a 200.0 mL buffer
containing 0.100 mol C6H5NH3Cl and 0.500 M
C6H5NH₂. The value of Kb for C6H5NH₂ is 4.3 x
10-¹⁰.
Use the table below to determine the moles of
reactant and product after the reaction of the
acid and base. You can ignore the amount of
liquid water in the reaction.
C6H5NH3(a OH-(aq) → H₂O(l) C6H5NH₂ (ac
Before (mol)
Change (mol)
After (mol)
