A solution of the weak base, aniline, C6H5NH2, in 25.0 mL of water requires 25.67 mL of 0.175 M HCl to reach the equivalence point.
C6H5NH2 (aq) + H3O+ (aq) <---> C6H5NH3+ (aq) +H2O (l)
What was the concentration of aneline in the original solution?
What are the concentrations of H3O+, OH-, and C6H5NH3+ at the equivalence point?
What is the pH of the solution at the equivalence point?
