The compound trimethylamine, (CH3)3N, is a weak base when dissolved in water. Write the K₁ expression for the weak base equilibrium that occurs in an aqueous solution of trimethylamine: Kb =

Many important biochemicals are organic acids, such as pyruvic acid (pka = 2.5) and lactic acid (pka = 3.86). For each acid, draw a simple titeation curve, and label the pKa. Draw an arrow where the line crosses pH 3 for each acid? Calculate the percentage of acid and conjugate base for both at pH 3..
