Proton Transfer in Liquid Ammonia Solutions Containing Water and Hydroxide Ion

The rate of proton transfer in ammonia solutions containing water and hydroxide ion was determined as a function of temperature and concentration by means of PMR spectroscopy. A first order dependence on hydroxide ion and second order dependence on water concentration was found with a rate constant of k₃ = 6.1 ± 1.2 × 10³ M^?2 sec^?1 at 25°C and ΔE^? = 4.5 ± 0.5 kcal/mole. The value of k₃ is in good agreement with that reported by other workers.
