Other Condition: at high temperature
Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.
Add a few drops of nitric acid solution into a test tube containing the platinum sample, heated over an alcohol lamp flame
Nitric acid is one of the strong oxidizing acids. It oxidizes most metals, including weak reducing metals such as Cu, Ag, etc. except Au and Pt.
