WebJul 26, 2014 · Below is a typical curve for the titration of glycine with NaOH. Although we often write glycine as NH₂COOH, it is really a zwitterion, + NH3CH2COO⁻. The fully protonated form of glycine is + NH3CH2COOH. Step 1 is the loss of H+ from the carboxyl group. Step 2 is the loss of H+ from the less acidic NH+ 3 group.

Calculate the equivalents of b that remain. From this you will get pOH. [ O H X −] = b − a V 1 + V 2. If a > b, then resulting solution is acidic. Calculate the amount of a that remains. game torrent cities skylines
