1) 10 mL of 0.05 M amino acid (Ka1=4.69x10^-3 and Ka2=1.79x10^-10) is titrated with 0.05 M HCl. Sketch a titration curve. (there's no need to actually sketch the curve; I just need to calculate the pH values needed to sketch a curve)
2) What if the HCl was 0.1 M?
3) What if the amino acid was 0.1 M?
