I am performing a titration to identify an unknown ammino acid that is either a diprotic or triprotic acid. Prior to the experiment, the amino acid is initially dissolved in 75ml of water. Based on the results of the titration below, it would appear that one of the equivalence points would be at pH 5.42, even though it is the initial pH of the unknown acid before any titration was performed. Please explain why, along with a graph.
