WebOct 6, 2024 · The titration curve of TPP showed two clear equivalence points, and an average chain length of 2.7 was calculated, close to its theoretical value of 3. 31 P-NMR … WebOct 1, 2005 · D.K. Total and free acid values are often measured and used to control phosphate systems, which are acidic by design (to initiate the phosphate reaction). The first titration would be for free acid. This would involve taking a bath sample and titrating it with a known standard such as sodium hydroxide (probably 0.1N or 1.0 N).
