Brass not reacting to nitric acid
WebThe formula for the reaction between the piece of copper and nitric acid is: 4 HNO3 (l) + Cu (s) ==> Cu (NO3)2 (aq) + 2 NO2 (g) + 2 H2O (l). The gas formed from Part A.2 is nitrogen dioxide and its chemical formula is NO2. The color of the gas is maroon, which is a mix of red and brown. Part D.1. WebJan 16, 2024 · You will get a little bit of copper nitrate from the reaction of the acid with traces of copper oxide or copper carbonate on the surface. But the copper metal will only react if you use concentrated nitric acid, or hot dilute nitric acid. You can use this to make a two-tone effect when etching brass plate.
