Attempt Titrating Amino Acid Against Weak Base

Attempt titrating an amino acid against a weak base and discover the number of dissociating (ionisable) functional groups in the amino acid.

Answers:

When an amino acid is titrated against a weak base, it dissociates and gives two functional groups.

(i) —COOH group (carboxylic group)

(ii) Amino group (${ NH }_{ 2 }$ ).
