WebThe copper that is the primary component of the statue slowly underwent oxidation from the air. The oxidation-reduction reactions of copper metal in the environment occur in several steps. Copper metal is oxidized to copper(I) oxide Cu 2 O), which is red, and then to copper(II) oxide (CuO), which is black. http://kentchemistry.com/RegentsExams/regents_jan_2011_54_55.htm

Copper sulfide - Wikipedia

WebSep 22, 2024 · Copper (Cu) reacts with sulfur (S) to form copper sulfide as shown in the equation. A scientist adds 12.7 grams of Cu to 3.2 grams of S to start the reaction. In this reaction, all of the copper and all of the sulfur react. The scientist needs to determine … WebAug 21, 2024 · For example, if you react copper(I) oxide with hot dilute sulfuric acid, you might expect to get a solution of copper(I) sulfate and water produced. In fact you get a brown precipitate of copper and a blue solution of copper(II) sulfate because of the disproportionation reaction. \[ Cu_2O + H_2SO_4 \rightarrow Cu + CuSO_4 + H_2O\] WebWhen heat was added to the copper (II) sulfate pentahydrate it began to remove water from the substance. 2. As heat is being added, the substance that began as a blue crystal powder form becomes white. 3. Copper sulphate indicates both a physical and chemical change because the color changed from blue to white after heating and because it is ... patapsco state park cabin rental
