Abstract

A crystalline sample of 5-amino-1H-tetrazole synthesized by us was used. The enthalpies of solution of crystalline 5-amino-1H-tetrazole in an aqueous KOH solution at 298.15 K were measured by a direct calorimetric method. The equilibrium composition of the system, including the stepwise dissociation of 5-amino-1H-tetrazole and water dissociation, was calculated using the KEV program. The standard enthalpies of formation of 5-amino-1H-tetrazole and its dissociation products in aqueous solution were calculated.
