Handle with care. The characteristics of copper, and the reaction of the metal with nitric acid Stable metal Vs. Strong oxidizer. Madison:
The chemical reaction between the copper and the nitric acid produces heat. With a high oxidative strength, nitric acid will completely dissolve copper, turning it green and then blue as the metal wears away in a matter of minutes. Why and how do you say nitric acid is an oxidizing acid from copper and nitric acid reaction? is reduced to nitrogen dioxide, a poisonous brown gas with an irritating odor: Cu(s) + 4HNO3(aq)
(Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies.) In this lab exercise you will start with copper metal and perform a series of reactions, ending with recovery of the copper metal (hopefully!). John Emsley, The Elements, 3rd ed. Charles' Law As the temperature from the reaction warms the gas, it expands. It is a colorless gas. Oxford, Clarendon Press,
