A sample of 25.00 mL of .200M Butyl amine in a flask, (find Kb for this amine in literature) is titrated with .10 M HNO3 solution at 25 C.
The base dissociation reaction is:
CH3CH2CH2CH2NH2 + H20 <-> CH3CH2CH2CH2NH3 + OH
the acid-base reaction is:
CH3CH2CH2CH2NH2 + H <-> CH3CH2CH2CH2NH3
1. caculate the volume of the acid soultion needed to completly neutralize the base in the flask
2. Caculate the pH for (a) the inital base solution in the flask; (b) the point at which 20mL of the acid has been added; (c) the equivalence point, and (d) the point at which 40.00 mL of the acid has been added.
