Get … List the hazards involved in this experiment. Most chemical reactions are exothermic. 8 comments. Upon reaction with nitric acid, most metals give the corresponding nitrates. Some metalloids and metals give the oxides; for instance, Sn, As, Sb, and Ti are oxidized into SnO 2, As 2 O 5, Sb 2 O 5, and TiO 2 respectively. When all the copper(II) oxide has been added, continue to heat gently for 1–2 minutes to ensure reaction is complete. It is important to note that with any type of mixture involving acid one should be extremely careful. Reaction 1: Copper and Nitric Acid Copper metal is not generally soluble in acid because copper is a stronger reducing agent than hydrogen, that is, copper metal will not reduce H+ to H 2. Nitric acid is an oxidising agent and the reaction is not the usual acid + metal reaction. Answer Save. It may be wise to check (using pH or litmus paper) that no acid remains. In the HOOD, add 2 mL of 6M nitric acid to the beaker and warm the contents on a hot plate. This is the acid of commerce and is the easiest to handle and transport. Name the gas produced when nitric acid is added to copper metal. Nitric Acid Reaction Types . Chemistry Chemical Reactions Chemical Reactions and Equations. The sequence begins with copper metal and ends with copper metal, so it is called a cycle of copper reactions. Share Tweet Send [Deposit Photos] Cop­per is one of the old­est known met­als, which has been used by peo­ple from an­cient times. What im not understanding is where the H20 and 2NO2 came from? We have already briefly explained this. During the early period after emplacement, the container could be exposed to a humid, aerated, and irradiated environment containing nitric acid. The sequence begins with copper metal and ends with copper metal, so it is called a cycle of copper reactions. Nitric acid and calcium hydroxide ---> calcium nitrate and water 2HNO 3 + Ca(OH) 2---> Ca(NO 3) 2 + 2H 2 O. Ethanoic acid and sodium hydroxide ---> sodium ethanoate and water (Acetic acid and sodium hydroxide ---> sodium acetate and water , using the older names) CH 3 COOH + NaOH ---> NaOOCCH 3 + H 2 O.
