The enthalpy of formation of MoF6(l) by solution calorimetry

open access: bronzeJournal of Research of the National Bureau of Standards, 1978
Enthalpies of reaction of MoF6(ℓ) in NaOH solutions, of MoO3(cr) in NaOH solutions, of NaF(cr) in MoO3-NaOH solutions, and of NaF(cr) in H2O(ℓ) were measured to obtain the enthalpy of reaction of MoF6(ℓ) in infinitely dilute NaOH solution: MoF 6 ( ℓ ) + 6   OH - ( aq ) = MoO 3 ( cr ) + 6   F - ( aq ) + 3   H 2 O ( ℓ ) Δ H ∘ ( 298.15   K ...
