In the present study, activities of silver are directly measured by employing a solid-state EMF method, by using AgI as the solid electrolyte. The EMF was determined using a galvanic cell (-) Pt | C | Ag | AgI |Ag-Au-Pd alloy | C |Pt (+) , which produced novel experimental data on the thermodynamic properties of Ag–Au–Pd alloys. Darken method was used to calculate integral excess thermodynamic properties from the data. New thermodynamic characteristics, such as integral excess mixing Gibbs energy, entropy and enthalpy of the Ag–Au–Pd alloys, have been generated in a temperature range of 475 and 675 K. Isoactivity lines of silver in the system have been drawn throughout the Gibbs triangle. Thermodynamic properties of the binary Au–Pd alloys have been compared with the previous investigations.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]EMF method,Entropy and enthalpies,Fundamental physics,Galvanic cells,Low temperatures,Temperature range,Thermodynamic characteristics,Thermodynamic data[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors are indebted to Indonesian Government that provides the LPDP scholarship.
