Abstract: Solid state chemistry has been one of the most extensively studied subjects in the recent two decades. However, in the past, chemistry-major students did not have much training on solid state reactions and the techniques of physicochemical studies on solid state materials. This designed experiment employed a simple red-ox reaction of tungsten oxide (WO₃) to demonstrate a typical solid state intercalation reaction and techniques of conductivity measurements. Some general concepts in solid state chemistry, such as intercalation, categorizing of materials based on conductivity, and charge transport properties of solid state materials are also introduced.
