The pH of an aqueous solution containing aniline, C6H5NH2, and its salt anilinium chloride C6H5NH3Cl, is 4.20. The concentration of aniline is 0.50 M. The dissociation constant Kb, for aniline is 4.27X10^-10. The anilinium chloride will totally dissociate to form the anilinium and chloride ions.

a. Calculate the concentration of anilinium ion, C6H5NH3 in this buffer solution

b. Calculate the pH after 4.00g of NaOH is added to 1.00L of the above buffered solution. Assume that there is no change in the volume of the solution upon addition of NaOH.
