General description

Platinum (Pt) is a highly ductile, malleable and unreactive metal. It is resistant to corrosion and stable at high temperatures. Although resistant to hydrochloric and nitric acid, it dissolves readily in hot aqua regia to form chloroplatinic acid.

Application

Mixtures of hydrogen in air was converted to water on a heated platinum surface. Pt may be used :
  • as a microelectrode-indicator electrode in voltammetry
  • to study chronopotentiometry of hydrogen peroxide with a platinum wire electrode or
  • in gas detection instruments.
  • as electrode in spectrochemical cell to measure the electrochemical properties of aqueous solutions of epinephrine, dopamine, and norepinephrine.
