aluminum and copper sulfate reaction

Once you can't see anymore Aluminum, heat an additional 3 to 4 minutes, then remove from the heat. This means that the oxide reacted with the salt. Remove the filter paper from the funnel and spread it out on a paper towel to dry overnight. Students add aluminium cooking foil to copper(II) sulfate solution and observe no reaction. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Demonstrations › Chemical Reactions II › 5.6. By introducing NaCl, the reaction happens. This is your actual yield of copper. An example will be the otherwise. Conditions for Reaction to Occur : Both Aluminum Sulfate and Sodium Hydroxide are soluble. Record the mass exactly into the data table (thousandths place). Al2O3 + 6NaCl -> 2AlCl3 + 3Na2O. Include state symbols. Calculate the percent yield of the experiment. Stirring frequently allow the reaction to occur until you can't see anymore aluminum. Our lab is a prime example of what NOT to do. This will take 15 to 20 minutes so be patient. react the the sample of aluminum foil and copper sulfate pentahydrate in an aqueous medium sized beaker; stirring frequently. I think it was part of the bare aluminium that was reacting with water producing hydrogen gas but I'm not sure. Write a balanced equation for the reaction of copper sulfate with aluminum. measure amount of copper sulfate pentahydrate. © copyright 2003-2020 Study.com. Which is the correct balanced equation for copper(II) sulfate + aluminum --> aluminum sulfate + solid copper? Rinse out your beaker with a small (amount just covering the bottom of the beaker) of water to be sure you obtained all of the product/residue. Answer to: Write a balanced equation for the reaction of copper sulfate with aluminum. Chemical Reactions II: Oxidation/Reduction. Our experts can answer your tough homework and study questions. {eq}\rm 2 \ Al \ _{(s)} \ + \ 3 \ CuSO_4 \ _{(aq)} \ \rightarrow \ Al_2(SO_4)_3 \ _{(aq)} \ + \ 3 \ Cu \ _{(s)}\\ with a glass stirring rod, stir the solution until the copper 2 sulfate pentahydrate is dissolved. Be sure the propane is turned of and Bunsen burner disconnected and put away. {/eq}SO{eq}_4 When you put aluminum in copper chloride, the copper together the chloride eats away at the aluminum. Clean and dry the glassware. We performed the lab according to everything we were supposed to do, but we missed one minor detail. What is the reducing agent and what is the oxidizing agent? 5 H2O) and record the mass in the data table. Write your names around the edge of a filter paper (so you can claim it later), weight and record the mass in the data table. This experiment illustrates the displacement of copper from copper(II) sulfate solution using aluminium foil. Theory: In order for a single displacement reaction to occur, an element and a compound need to be present. {/eq}. Jasmine, Ashley, and Courtney's Chem Reports! Reducing: Aluminum; Oxidizing: Copper Sulfate Pentahydrate. Again the aluminium doesn't react with copper sulfate due to the oxide layer. 5.6 Reduction of Cu 2+ by Aluminum. Upon returning the next day, weigh the filter paper and dry residue and record the mass in the data table. Written on the board was the measurement of 0.4-0.7 grams of Aluminum, but we were mistaken for we did not see the decimal point. This reaction that I found online produces a salt and an oxide from a salt and an oxide. Give three reasons of why the amount of copper that should have formed and the amount of copper that actually formed might be different. What type of reaction is this? At first the lab seemed fine and everything was going according to what was said would be done. The following is the balanced equation for this reaction. But how? Aluminum & Copper II sulfate Redox Lab Introduction: The purpose of this lab is to find out the number of grams of copper that will be formed from an oxidation reduction reaction when you know the mass of Aluminum that reacted with a known amount of copper 2 sulfate pentahydrate and to compare this to the actual yield of copper. Include state symbols. Carefully weigh out the powder to weight between 0.4-0.7 grams. Measure out 10 g of Copper 2 Sulfate pentahydrate ( CuSO4. Services, Single-Displacement Reaction: Definition & Examples, Working Scholars® Bringing Tuition-Free College to the Community. There is noticeable burning smell and some faint smoke as a result of the chemical reaction. Aluminum & Copper(II) Sulfate Redox Lab Introduction: The purpose of this lab is to determine the number of grams of copper that will be produced from an oxidation reduction reaction when you know the mass of Aluminum that reacted with a known amount of copper 2 sulfate pentahydrate and to compare this to the actual yield of copper. {/eq}) and copper metal are produced. {/eq}) reacts with aluminum (Al) metal, aluminum(III) sulfate (Al{eq}_2 For the reaction we show them in the aqueous state. Then slowly add the crystals to the heating water. A vigorous displacement reaction occurs and the solution gets very hot, aluminium dissolves and red copperis visible. aluminum: aluminum sulfate: hydrogen gas: J. potassium iodide: chlorine gas: potassium chloride: iodine gas . But then our solution bubbled to such an exceeding amount that it overflowed the beaker and spilled all along the counter-top. We have learned a valuable lesson from this mistake and we would advise that you learn from our mistake as well and not make it yourself. We have learned to properly read directions and properly weigh the material placed in the concoction. Reactions wherein one element or species substituted for another element or entity in a compound, producing a new compound and removing the replaced element, are referred to as single-displacement reactions. filter, dry and weigh the resulting product. Is this step the reason why then the whole reaction can take place? All other trademarks and copyrights are the property of their respective owners. Then sodium chloride is added and dissolved. Which is the correct balanced equation for copper(II) sulfate + aluminium --> aluminium sulfate + solid copper? Al + CuSO4 --> Al2(SO4)3 + Cu… Use the filter paper and your funnel to filter the residue in the beaker, catching the filtrate into the Erlenmeyer flask provided. Mass of Copper(II) Sulfate Pentahydrate, Mass of dry residue/product + Filter Paper, like the color and all in all a good blog, maybe make the pictures a little bigger and fix the "font-background contrast" ;), good lab. Answer to: Write a balanced equation for the reaction of copper sulfate with aluminum. {/eq}){eq}_3 Oxidation: Al(s) → Al3+(aq)+ 3e−. When solid Ni metal is put into an aqueous... Synthesis Reaction: Definition, Formula & Examples, Double Displacement Reaction: Definition & Examples, The Activity Series: Predicting Products of Single Displacement Reactions, Decomposition Reaction: Definition & Examples, Combination Reaction: Definition & Examples, Combustion Reaction: Definition & Examples, Writing and Balancing Combustion Reactions, Biochemical Reactions: Synthesis and Decomposition, Rate of a Chemical Reaction: Effect of Temperature, What Is a Chemical Reaction? 78.1g Cu = (actual)/4.3 Al2(SO4)3 = 335.83. The Sodium Sulfate is soluble and … Use the Mass of the Aluminum powder and calculate the mass of the copper you theoretically would form. What type of reaction is this? All rights reserved. When copper sulfate ({eq}\rm CuSO_4 Explanation: The reaction would be the following : 2Al(s) +3CuSO4(aq) → Al2(SO4)3(aq) +3Cu(s) This is an oxidation-reduction reaction were electrons are transferred from Aluminum Al which get oxidized to Copper Cu2+ which gets reduced. While the copper Sulfate Crystals are dissolving one member of the group can go and get the Aluminum Powder.
