Abstract: The standard molar formation enthalpies of (A+)2Cd2(SO4)3[A+ is NH+ 4 or K+] are determined from the enthalpies of dissolution (ΔsHm) of [(A+)2SO 4(s)+2CdSO4(s)] and (A+)2Cd2(SO4)3(s) in twice distilled water or 3 mol•L-1 HNO3 solvent respectively,at 298.2 K,as: ΔfHm [(NH4)2Cd2(SO4)3,s,298.2K]=-3031.74±0.08 kJ•mol-1 ΔfHm [K2Cd2(SO4)3,s,298.2K]=-3305.52±0.17 kJ•mol-1
Key words: Double sulfate salts, Solution calorimetry, The standard molar enth alpy of formation
