Copper Cycle Lab Essay

enjoymentDuring this experiment, we were trying to see whether horseshit, after a chain of chemical reactions, bequeath revert back to its elemental form.ProcedureFirst, I added nitric venomous with copper in a beaker, which sour into a copper nitrate, a blue-green beginning. subsequentlywards, I added sodium hydroxide, and my resolvent colored to a glowering blue solution called copper hydroxide. I heated the solution to meld the water and I got a brownish-blackish warm called copper oxide. Once the solid appeared, I poured in sulfuric vinegarish to it and I got copper sulfate, a bluish solution. The final step I took was to add the element zinc, which turned the solution from blue to clear, with a brown solid in the shag of the beaker, copper.ObservationDuring each step, something happened. For instant, for the first step, when I added the acid to the copper, the copper disappeared and the solution turned from the clear acid color to a blue-greenish hue. In the succee ding(a) step, there was another chemical reaction when I added the sodium hydroxide. The in all solution turned blue when I stirred the mixture. When the time came to vanish the solution, the liquids disappeared, leaving behind a wet, brownish solid in the midway of the beaker. When the solid was hot, it bubbled and popped until it cooled down. When all the liquids evaporated, I scraped off the solid and put it in a separate beaker. Once I put the sulfuric acid in it, the brown solids (copper oxide) slowly dissolved and turned the acid into blue. After the acid was blue, I added the metal/grey colored zinc into the solution the solution bubbled and the zinc turned the solution clear. The zinc disappeared and in its place, copper appeared.AnalysisFor each step, there was a chemical reaction, except for the get down where we evaporated the water/liquefied chemicals. For each step, I was turning the copper into a compound. When an acid was added to the copper, it turned the element into a compound. When a base was added later, it that replaced the acid with the base.ConclusionFor this experiment, I bum conclude that an element/ guinea pig can never be destroyed or created. The copper round of golf is evidence for the Law of Conservation of Mass, which states that an element or matter can never be created or destroyed, only changed.
