Yeah, I don't know how to do titrations very well so I thought I'd come here first #_#

@Woodward i'm not good at these either.. do you know @cuanchi that guy is amazing at these types of questions. I'm going to look this over myself

photon336 · Answer

well for starters, $$M _{1}V _{1} = M_{2}V_{2}$$

Since its a diprotic weak acid it will have 2 Ka values. 
We can consider the neutralization of alanine here .
