a) Find the pH at the equivalence point when 40ml of 0.025 M of methylamine (NH2CH3 and Kb = 4.4x10^-4) is titrated with 0.025 M HCl.
b) The Kf for the complex ion Ag(NH3)2+ is 1.7x10^7. The Ksp for AgI is 1.5x10^-16. What is the molar solubility of AgI in a solution that is 2.0 M in NH3?
c) Find the percent ionization of a 1.00 M solution of formic acid (HCOOH) when Ka = 1.7x10^-4.
