WebThis was also confirmed by the inability to perform acid–base titration on phosphorylated cotton cellulose. The potentiometric titration curve does not show the expected jump when titrating a crushed sample with a KOH solution. This fact proves that there were no functional phosphorus-containing groups with hydrogen that could be substituted.
