Copper turnings experiment
WebOnce all of the copper has reacted, the solution is diluted with distilled water, changing the solution from a dark brown to a pale blue color. This demonstration can be done with copper in the form of shot, pellets, … WebIn this experiment, students react an insoluble metal oxide with a dilute acid to form a soluble salt. By reacting copper(II) oxide, a black solid, with colourless dilute sulfuric acid, they produce copper(II) sulfate with a characteristic blue colour. Students can then obtain blue copper(II) sulfate pentahydrate crystals

WebNov 24, 2024 · Solid copper is oxidized with HNO₃: Cu + 4HNO₃ → Cu²⁺ + 2 NO₃⁻ + 2H₂O + 2NO₂. Where 1 mole of Cu produce 1 mole of Cu²⁺ when nitric acid is in excess. Moles of Cu that react (Molar mass Cu = 63.546g/mol): 0.94g * (1mol / 63.546g) = 0.0148 moles of Cu. And moles of Cu²⁺ produced are also: 0.0148 moles WebABSTRACT The purpose of this experiment was to cycle copper through a series of different chemical forms by reacting the copper with different chemicals.
