ethylene glycol is polymerizes with an impure sample of terephthalic acid which contains 1.0 mol% benzoic acid. how do these impurites affect the limiting degree of polymerization at very high conversion? (by stoichiometric imbalance)
Homework Answers
after the addition of benzoic
acid to the polymer chain the polymerization stops because there is
no -COOH group left for the ethylene glycol to further react
with.

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
