Bicine $(N,N-$bis $(2$ hydroxyethyl glycine$)$ is another commonly used buffer in biochemistry labs. The structure of the bicine in its fully protonated form is shown below. Draw the titration curve for bicine, assuming the pKa for its free COOH group is $2\mathrm{.}3$ and the pKa for its tertiary amino group $(NH+)$ is $8\mathrm{.}3$ Include the isoelectric point in your curve, DRAW THE CURVE AND LABEL THE ISOELECTRIC POINT ON THE CURVE PLEASE!
