a. calculate the concentration of C6H5NH3+ in this buffer solution.

first we need the dissociation constant for the weak acid or base http://www.zirchrom.com/organic.htm is a good reference and from that I find pKa is 4.63

This correspomds to the following reaction: C6H5 NH3(+) = C6H5NH2 + H(+)

I am going to drop the C6H5 part in my derivation and call this reaction:

-NH3(+) = H(+) + NH2 The ka is given by [H][NH2]/ ...
