• Resumen

  • An experiment is described that allows students to experimentally determine an empirical formula for silver sulfide. At elevated temperatures, silver sulfide reacts in air to form silver, silver sulfate, and sulfur dioxide. At higher temperatures (~960 °C) silver sulfate decomposes to produce metallic silver.
