Calculation of proportion of zwitterion from this please.
(I shouldn't answer this because it is a homework question with no effort, but since someone posted a wrong answer I'm answering anyway)

Only the pK of 9.6 is relevant because the pH is 10.6; therefore, think of the situation as having just two species, zwitterion (acid) and negative (conjugate base).

Because pH is one unit above the pK, the ratio of acid to conjugate base is 1 to 10. 

Ratio of acid to total is 1 to 11.

1/11 = 0.0909
