Demonstrations - Copper + Nitric Acid

Copper is a reddish-brown metal, widely used in pluing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny. (Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies.) Copper is oxidized by concentrated nitric acid, HNO 3, to produce Cu 2+ ions; the

Action of Nitric Acid on Metals - Atomistry

The function of nitrous acid in starting the reaction between these metals and nitric acid is that of a depolariser. Very few metals can be used as containers, etc., for nitric acid, but aluminium seems to have possibilities in this respect, and the action of nitric acid on this metal has received much attention.3 Temperature and concentration are the chief factors, and it would seem that
