What volume (in milliliters) of 0.200 M NaOH should be added toa 0.125 L solution of 0.027 M glycine hydrochloride (pKa1 = 2.350,pKa2 = 9.778) to adjust the pH to 2.71?
NH3 is a weak base (Kb = 1.8 à 10â5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.027 M in NH4Cl at 25 °C?
