Abstract

The reaction between formic acid and HOBr in strongly acid aqueous media was studied by absorption spectrophotometry at 298 K. Bromine, the monitored species, displays a transient behavior, gradually rising up to a maximum and then decaying with first-order kinetics. Reaction rates, expressed as R = -dC_(Br_2)/dt, depend on the concentrations of HCOOH (0.1–1.4M), HOBr (0.3–1.5 × 10^(−3)M), and H^+ (0.1–1.0M). The mechanism (1) HOBr + HCOO^- = Br^- + CO_2 + H_2O (2, -2) H^+ + Br^- + HOBr ⇌ Br_2 + H_2O (3) Br_2 + HCOO^- = 2Br^- + CO_2 + H^+ with k_1 =1.04 ± 0.20M^(−1) · s^(−1), k_3 = 20.2M^(−1), quantitatively accounts for all observations within experimental error.
