Abstract

Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 kcal / mole , NH 4 ClO 4 ( c ) , = - 295.98 ± 1.35 kj / mole = - 70.74 ± 0.32 kcal / mole , NaClO 4 ( c ) , = - 382.75 ± 0.93 kj / mole = - 91.48 ± 0.22 kcal / mole . A brief summary of other recent data has been included.
