Question

N + ​ H 3 ​ − CH ( R ) − CO 2 ​ H has its Ka 1 ​ = 1 0 − 7 . pKa 2 ​ of this is 9.4 , at which pH this amino acid will not migrate towards any electrode during electrolysis :

TestHub · Accepted Answer

At isoelectric point amino acid will not migrate towards any electrode during electrolysis. Isoelectric pH of a aminoacid = 2 p K a 1 ​ + p K a 2 ​ ​ ∴ pI = 2 7 + 9.4 ​ = 8.2 Ans: B]
