Molar heat capacity measurement of CaHCl and CaHBr

Molar heat capacities of two hydride ion conductors, namely, CaHCl and CaHBr, were measured by differential scanning calorimetry. The measured molar heat capacity data of these compounds as a function of temperature is given by the following expressions: C p (J K −1 mol −1 ) = 57.806 + 16.420 × 1...

description	Molar heat capacities of two hydride ion conductors, namely, CaHCl and CaHBr, were measured by differential scanning calorimetry. The measured molar heat capacity data of these compounds as a function of temperature is given by the following expressions: C p (J K −1 mol −1 ) = 57.806 + 16.420 × 10 −3 .T − 1.006 × 10 6 .T −2 (308–748 K) C p (J K −1 mol −1 ) = 56.534 + 44.880 × 10 −3 .T − 1.481 × 10 6 .T −2 (323–713 K) From the above expressions, molar enthalpy increments, entropies and Gibbs energy functions of these compounds were derived and reported. Graphic abstract SYNOPSIS CaHCl and CaHBr are hydride ion conducting solid electrolytes find application in electrochemical hydrogen meter to determine dissolved hydrogen concentration in liquid sodium. Heat capacity of CaHCl and CaHBr were measured using DSC and reported.
