Chemistry Son! BooYah!
Tuesday, May 18, 2010. Aluminum and Copper Sulfate Yield Lab. In Chemistry, percent yield is used to show. What materials you have left and how much leeway you have in an experiment। This is a really great tool for scientists to use. It gives them a chance to see how much of a substance produces with the limited materials. With all this in mind, How does Aluminum take the place of Copper in Copper (II) Sulfate? I predict that Aluminum and copper switch places because of Single Displacement. 4 with a glas...

Chromatography Lab
Thursday, February 4, 2010. In this lab we tried to discover which solvent ,(out of four), had the highest retention time. We wanted to see which solvent was able to separate the pigments of the color continuum the best. We also wanted to see which pigments were in each of several different colors. Hypothesis: That H2O (water) would be the best solvent to retain the black ink and it would have the highest retention time, (therefore better demonstrating the color continuum.). When the solvents retain the ...

Period 3 Group 19 Station 8 Lab Report. Thursday, May 20, 2010. Alluminum and Copper II sulfate Redox Lab. Aluminum and Copper II sulfate Lab. Statement of the Problem:. 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 II sulfate pentahydrate. And to compare this to the actual yield of copper? Aluminum foil , Copper II sulfate pentahydrate. Medium sized beaker, stirring.

Thursday, May 20, 2010. We determined the number of grams of copper that was produced from oxidation reduction after we found the mass of Aluminum that reacted with our known amount of copper II sulfate (.31) pentahydrate and compared those to the actual yield of copper. We obtained a medium sized beaker (250 to 400mL.)Then we added 150 to 200 mL of water to the beaker, then we began heating over a Bunsen burner. 100 mL H2O - - - 60 mL. We then carefully added alumium to the hot solution with continuous ...

Lhs chem 4 lab station 11. Thursday, May 20, 2010. We would expect to find Copper II sulfate pentahydrate to go through a single displacement oxidation reduction reaction where aluminum would exchange with copper and form aluminum sulfate. Therefore, leaving behind copper which will later be filtered out and weighed. Medium sized beaker about 250-400 ml. 10 grams of Copper II sulfate pentahydrate. 424 grams Aluminum powder. Filter paper two sizes. Mass of Copper II sulfate pentahydrate=10g. This lab help...

Jasmine and Ashley Chem Reports. Tuesday, May 18, 2010. Aluminum and Copper (II) Sulfate Redox Lab. Aluminum and Copper (II) Sulfate Redox Lab. To determine the number of grams of Cu that will be produced from an oxidation reduction reaction when you know the mass of Al that reacted with a known amount of CuSO. O and to compare this to the actual yield of Cu. In our lab, we found that Al is the limiting reactant (Al - 0.003 mol Cu; CuSO. Medium sized (75-100ml) beaker. On weighing paper. I took it ba...

Our Fantastic Lab Reports! Tuesday, May 18, 2010. Aluminum and Copper(II) Sulfate Redox Lab. 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. Measured sample of aluminum foil. Measure amount of copper sulfate pentahydrate. Obtain a medium sized ( 80 ml) beaker. Stirring freque...

Lhs lab report blog. Link to Howell Space. Thursday, May 20, 2010. In this lab we will be mixing aluminum powder with a mixture of copper sulfate and water. The purpose of this lab is to measure out different quantities of chemicals and along with there molar mass incorporate those numbers into equations that will give us info such as the limiting reactant, percent yield, and theoretical yield. With this lab you are also given the opportunity to observe multiple chemical reactions. 412g Al X 1 mol Al/26&...

Thursday, May 20, 2010. Al and Cu II Sulfate Redox Lab. The purpose of this lab was to determine the number of grams of copper that will be produced for an oxidation reduction reaction when you know the mass of Aluminum that reacts with a known amount of copper II sulfate pentahydrate and to compare this to the actual yield of Copper. 1Obtain a 250 to 400ml sized beaker. 2Add 150 to 200ml of water to 250 to 400ml beaker; set-up apparatus to heat your mixture over a Bunsen burner to begin heating. 9Use th...

Tuesday, May 18, 2010. Aluminum and Copper (II) sulfate Redox Lab. Safety Precaution- Make sure you put on safety glasses and wear an apron. The weight of the product that was filtered out is .71 grams. Thing in this lab that could have messed with our results could have been the error in the amount of each substance we put in the water. The ratio could have changed our results. In order to get an actual answer we would have to repeat the lab multiple times and get and average. Tyson Seth and Sthuler.

Lab Report Blog 4 9. This is super cool because thats just the way we are so totally drop us a message. Tuesday, May 18, 2010. Aluminum and Copper II Sufate Redox Lab. The purpose of this lab is to better understand the application of stoichiometry. we will be testing materials of known amounts to determine the limiting reactants of the stoichiometry problem we solved. We will then cross reference our results with our expected results from the equation to see the percent yield. 8 We wrote our names aroun...
