Electromotive Force Measurements

Amalgams containing up to 60 wt.% indium are liquid and homogeneous at room temperature. The emf's of liquid amalgams containing from 10 to 50 wt.% of indium in the cell In/InCl3/amalgam have been determined and from these the quantities ΔG, ΔH, and ΔS for the process In + Hg → amalgam.

The first and second dissociation constants of malonic acid in different composition of (ethylene glycol-water)%, (10, 20 and 30)% mixed solvent determined using the electromotive force measurements of galvanic cells without liquid junction at nine different temperatures,  at  interval, including the body temperature. The value of the first and second thermodynamic dissociation constants have been used to determine the thermodynamic quantities of two dissociation processes. These quantities involved the standard free energy,  standard enthalpy change,  standard entropy change,  and standard heat capacity change.
