So Close =/

Overall: I titrated three corn oil samples, one water sample, and three saliva and corn oil swirled in my mouth for 10 minute samples. Dr. Splawn and I used a different pH meter to titrate four 10 minute samples which included: the procedure from yesterday, just the yellow color mixture, just the white color mixture, then one of just the entire sample that I spat out of my mouth. None of them showed a titration inflection curve line thingy.
