Tyrosine is a triprotic weak acid, with pKa1=2.41, pKa2=8.67, and pKa3=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 *Please show all work and not just answers, I'm looking to understand how to solve problems like these!

Applications of Molecular Spectroscopy

When light sources pass through the diffraction grating then light splits into different wavelengths. The light source produces two types of patterns that are shown as destructive and non-destructive. The light source is in the form of quanta that is quantitation.
