What is the ph at the isoionic point what is the ph at the

Assume that a solution contains a formal concentration of 0.010 M of the amino acid cysteine.

a) What is the pH at the isoionic point?

b) What is the pH at the isoelectric point?

c) Explain the difference between your answers in (a) and (b), including specifically why one result is larger than the other.

Cysteine
Ka1= 2*10^-2 pKa1=1.7
Ka2= 4.4*10^-9 pKa2=8.36
Ka3= 1.82*10^-11 pKa3=10.74
