Hello,

I am stuck on a question concerning the titration of lysine.  The question is the following: If the titration of lysine is done by adding OH- to a solution that has 2 moles of lysine, how many moles of NaOH would have to be added to get to 2.5 equivalent?

The answer is 5 moles, but I do not see how to get there.  Wouldn't two moles of lysine have 6 equivalents in total?  How would you go about using that information to get to the answer?

I thank in advance for the help

Would it be possible to provide the exact wording of the question?
