The standard enthalpy of formation (f, Hm,298.2K= -1342. 11 KJ• mol--1 ) of the double salt of Zn2HIO6. 1. 25H2O was determined by calorimetry in a new model isoperibel reaction calorimeter. The calorimetric solvent is an acid solution consisting of 3 mol• L-1 HNO3.

Key words: Double salt, Thermochemistry, The standard enthalpy of formation, Zn2HIO6·1.25H2O
