2. Sulfanilic acid (NH₂C6H4SO3H) is used in manufacturing dyes. It ionizes in water according to the equilibrium equation: NH₂CH₂SO₂H(aq) + H₂O(l) ⇒ NH₂C₂H₂SO3(aq) + H₂O¹(aq) K₁=5.9x10 A buffer is prepared by dissolving 0.20 mole of sulfanilic acid and 0.13 mole of sodium sulfanilate (NaNH₂C6H4SO3) in water and diluting to 1.00 L. a. Compute the pH of the solution. b. Suppose 0.040 mol of HCl (assume volume does not change) is added to the buffer. Calculate the pH of the solution that results.
