Hydrated electron Boric acid

Buxton, G.V.; Sellers, R.M.
Radiat. Phys. Chem. 29, 137-140 (1987)

Reaction: e_aq^- + H₃BO₃ ® H· + H₂BO₃^-
Solvent: H₂O

k £ 5 × 10³(L mol^-1 s^-1), pH = 6.7

Experimental method: Pulse radiolysis
Analytical method: vis-UV absorption
Data type: Absolute value measured directly

Decay kinetics at 700 nm gave a rate constant consistent with impurity such as nitrate; no pH dependence was found for the decay rate in deaerated solution contg. 0.5 mol L^-1 boric acid.
