    • -3 M), 1 part of formic acid and 2 parts of hydroxamic acid are produced at pH 3.05. From the rate constants given in Table 6, at pH 3.05, 1 M phosphate, no hydroxylamine, about 2/3 of the reaction goes via the phosphate process. If all the reaction of phosphate is general base, then the amount of formic acid is 3 parts, and the amount of hydroxamic acid is 2 parts. If all the reaction is nucleophilic and the formyl phosphate reacts quantitatively with hydroxyl amine, then the amount of formic acid is 1 part and the amount of hydroxamic acid is 4 parts.
