The skeletal structures of the two amino acids, glycine and lysine, are given below along with the values of the relevant acid dissociation constants (pKa).


(a) For an aqueous solution of glycine alone, calculate the value of pH at which the ratio of the concentration of neutral glycine zwitterion to the concentration of protonated cation is 102.

Enter the numerical value of the pH:

pH= pKa2 + log(10^2) = 9.87 + 2 =11.87

but i still got it wrong. I am confused too.

i got the same result bt wrong

That's because you are using the wrong pKa
