Of reactions: the copper cycle of reactions known as the copper cycle the reaction series includes single replacement, double replacement, synthesis, and and then shares their findings with the rest of the class the lab is a qualitative rather than a quantitative experience, focusing on. Copper cycle lab #13 in this lab you will have an opportunity to observe a number of different types of chemical reactions and to write and balance some chemical equations. From copper to copper lab shakil m, horby l, shaquile p, fazal m april 17th 2012 mr vu chemistry introduction chemistry is the science of matter, especially its chemical reactions. Students may use lab notes recall what the final copper product on your filter paper looked like as well as the original copper sample used by your teacher how did the two samples differ in appearance the aluminum hook was involved in two reactions in the final step of the copper cycle show these reactions as balanced, chemical.
Copper cycle lab report introduction: the purpose of this experiment was to convert copper wire into different states using a variety of methods, including oxidation-reduction reactions and acid-base reactions then, at the end of the cycle, one should end up with solid elemental copper again, which theoretically has the same mass as the original sample. I hope you enjoy this video let me know what you think of the lab in the comments disclaimer: this experiment must be performed outside or in a fume hood. Copper cycle reminder – goggles must be worn at all times in the lab pre-lab discussion: five reaction types you should be able to recognize are synthesis / combination, decomposition, single.
Lab report for experiment 3 copper cycle olanrewaju oyindamola tuesday 27th february 2013 abstract this experiment is based on copper, to synthesize some copper compound using copper (ii) nitrate solution to obtain copper metal at the end. Actually, the nitrate ion oxidizes the copper metal to copper (ii) ion while itself being transformed to no 2 gas in the process the copper (ii) ion then binds to six water molecules the physical change you should observe is the copper-colored metal vanishing as the solution turns blue (from [cu(h 2 o) 6 ] 2+ , the hexaaquacopper ion) and a. Lab report #3: copper cycle abstract: the purpose of the experiment is to cycle solid copper through a series of five reactions at different stages of the cycle, copper was present in different forms first reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous the second reaction. The copper cycle lab procedure was designed to serve the aims of the investigation as it provided a sequential, listed set of instructions to which a student was meant to follow.
Copper cycle experiment 3 introduction one simple way to state the aim of chemistry is: the study of matter and its transformations in this experiment, a copper sample will appear in five different forms by going through four chemical reactions. Experiment 2 a cycle of copper reactions in the first experiment you had the opportunity to deduce and write the chemical formulas for some simple ionic compounds, and to use these formulas to represent simple chemical reactions. General chemistry lab #1 conservation of mass: a cycle of copper reactions purpose the goal of this experiment is to introduce you to several classes of chemical reactions: oxidation/reduction, precipitation, decomposition and acid/base neutralization.
According to the law of conservation of mass, the mass of the products must equal the mass of the reactants, so logically one would expect that if 2 g of copper was used to start the lab, the lab would result in 2 g of copper. Copper cycle lab observations reactants products cu (s) copper metal +hno3 (aq) nitric acid → n2o4 (g) dinitrogen tetroxide gas +cu++ (aq) aqueous copper(ii) ions 2 cu++ (aq) aqueous copper(ii) ions +naoh (aq) aqueous sodium hydroxide 4 → cu(oh)2 (s) solid copper(ii) hydroxide. Copper cycle lab report purpose: during this experiment, we were trying to see whether copper, after a chain of chemical reactions, will revert back to its elemental form procedure: first, i added nitric acid with copper in a beaker, which turned into a copper nitrate, a blue-green solution afterwards, i added sodium hydroxide, and my.
Chemistry lab report (copper cycle) this is a lab report for my general chemistry class the assignment was to create a formal lab report that expresses data and observations, lab procedure, and a discussion of the data with a conclusion. The copper cycle in this experiment you will start with a piece of copper metal, dissolve it in concentrated nitric acid, precipitate it as copper (ii) hydroxide, dissolve it in hydrochloric acid, and reduce everything back to copper metal.
Transcript of copper cycle lab report when heated, the copper hydroxide solid began to turn black, into a copper oxide in water when sulfuric acid was added to the copper oxide, the whole solution turned a blue color and no more black precipitate remained when solid granulated zinc was added to the copper sulfate, a single displacement. 4xlfn7lph dqgd decompressor are needed to see this picture the copper cycle lab class set the law of conservation of matter states that in a chemical reaction matter cannot be created or. I oxidizing copper metal with concentrated nitric acid, hno 3 (aq) the first step involves transforming cu metal to copper(ii) ions, cu 2+ , using concentrated nitric acid. Purpose/theory: the purpose of the experiment was to carry out a set of chemical reactions in order to illustrate the properties of copper and its compounds, the law of conservation of mass, and laboratory efficiency throughout the lab, we used our knowledge of key terms such as oxidation-reduction, single and double replacement reactions, and percent yield.
