2014-12-10 · The reactionbetween copper metal and concentrated nitric acid is an oxidation-reduction reaction that is somewhatcomplicated. 4 HNO3(aq) + Cu (s) => Cu (NO3)2(aq) + 2 H2O (l) + 2 NO2 (g) Identify the element or elements that undergo REDUCTION. Your Answer:c. Nitrogen, in 2 of the 4 moles of HNO3, is reduced from +5 to +4 in NO2.95%

The next step must be done in a fume hood because of the possibility of noxious gas being produced. Add 4.0 mL of concentrated nitric acid (a solution of HNO3). Swirl the solution around in the beaker until the copper has completely dissolved. Add water until the beaker is about half full. The remainder of the experiment can be carried out at your lab bench. Record in your notebook a description of everything …

2011-10-31 · As well as showing how dramatically copper reacts with nitric acid, this adapted demonstration also uses the high solubility of nitrogen dioxide to initiate a pleasing fountain.

Demonstrations - Copper + Nitric Acid

2010-9-29 · Copper + Nitric Acid Copper is a reddish-brown metal, widely used in plumbing 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 …

The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu 2 + ions. Copper is easily oxidized to Cu 2 +, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts. Because the nitric acid oxidizes the copper, the Nitric acid itself gets reduced.

2021-9-3 · Copper and Nitric Acid When concentrated nitric acid is dropped on a copper disk in the bottom of a glass cylinder, a reddish-brown cloud of nitrogen dioxide gas is rapidly evolved.

Copper and Nitric Acid Reaction | Cu + HNO3

Concentrated nitric acid and copper reaction | Cu + HNO 3 = Cu (NO 3) 2 + NO 2 + H 2 O Concentrated nitric acid reacts with copper and produce copper nitrate (Cu (NO 3) 2), nitrogen dioxide (NO 2) gas and water as products. In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide.
