Tyrosine is a triprotic weak acid, with pКа1-2.41, рКа238.67, and pКа3-11.01. a) calculate the final [OH-] of a solution that starts with .30M of the fully basic form. Do not assume the concentration of base is constant. b) at what pH range(s) would tyrosine act best as a buffer? c) calculate the pH of a solution at equilibrium which started with 0.043M at the monoprotonated H2A- form
