• Resumen

  • A mnemonic device has been designed for writing reactions of metals with nitric acid. The device utilizes a left hand and schematically indicates the product of reduction of nitric acid as a function of two factors: the activity of metal and the concentration of acid. Five different products can be retrieved with the help of the device. The integers represent the oxidation states of nitrogen in the resulting product of reduction. The device is particularly easy to memorize and use.
