Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 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 ...
