If you have already read about buffers in Theory section, it’s time to learn a bit about titration curves.
In Singapore 2012 we have to do a titration with unknown amino acid and find what is it from the standard curve made after titration. I found a similar lab protocol with answers so study it carefully.
Below you will find another practice problems with answers on the following file.
