The Process Of Recycling Aluminum From Cans Into Potassium Aluminum Sulfate

Using these concepts, in beaker 3, we were able to determine the exact amount Aluminum needed to react with 100% of the Copper present. During this experiment we used 0.707 g of CuCl22H2O to determine how much Aluminum is needed to react we use the equation below: As you can see from the equation above exactly 0.074 g of Aluminum is needed to fully react 0.707 g of Copper, however as you can see in table 1, 0.077 g of Aluminum was used. This can create a small amount of error due to the fact that it is extremely hard to measure an exact amount of Aluminum, although all the Copper was reacted in beaker 3, as could be seen by its clear solution with a small amount of grainy precipitate (Copper), Aluminum is in a small amount of excess, which could possibly affect the weight of the end product thus possibly causing error if the percent yield was

The objective of this lab was to use prior knowledge about the Law of Conservation of Matter and of different types of chemical reactions in order to evaluate if aluminum disappears during the reaction and copper appears. The reaction that occurred between Copper (II) Chloride and aluminum was a single replacement reaction. Clear signs that a chemical reaction took place include heat release/temperature change, color change, and formation of a precipitate. When a single element, in this instance aluminum, replaces another element in a compound, copper, a single replacement reaction occurs. A basic formula for these reactions is AB + C → AC + B.

In recycling, raw materials that have already been obtained are used, which reduces the need for more materials to be extracted. If we recycle enough to slow the rate of extraction bringing it lower or equal to the rate that our resources replenish themselves we are living sustainable. This project is especially important because it focuses on recycling objects that take a lot of resources to make and that can't be organically broken

Using elemental analysis to determine the percent mass composition of each element in a compound is the first step in creating an empirical formula. There are many different types of elemental analysis, but in this experiment gravitational analysis and Beer’s Law are used. Elemental analysis is first used to find the moles of each element, then converted to mass, and then the percent mass of the element in the product is found (2).

I started with elemental copper metal and then reactions occur step by step as follows:

The goal of the stoichiometry lab was to use stoichiometry and percent yield to compare how much product was supposed to be produced with how much was actually produced by experimentation. In this lab, the reactants aluminium and copper (II) chloride were used to form aluminium chloride and copper.

For the Synthesis of Alum lab my lab group and I took 1 gram of aluminum foil and broke it into small pieces. Next we added 25 mL of 3M KOH solution. Once the foil was dissolved we filtered the solution through a Buchner funnel with filter paper sealed inside with water. As the solution was filtering we applied a vacuum filtration to the Buchner funnel to expedite the filtering process. Once it was completely filtered my lab group poured the solution into a beaker and covered the beaker with parafilm. We then waited overnight to allow the crystals to form inside the beaker. Unfortunately, we did not produce any crystals overnight so we borrowed some from another group. Once we obtained the crystals we had to stir them in a beakers to make more form other than just the ones we received. After we rinsed the crystals with half ethanol and half water mixture. Once they were dry we determined the mass of the crystals with a balance.

Objective: The purpose of this lab is to demonstrate that scrap aluminum can be broken down to be reused to make useful materials. That aluminum oxidizes easily. Materials: 2.0g aluminum scrap 250 ml beaker 60 ml 1.5 M KOH

We are in the age of peak metals. Our sources for metal are rapidly running out. The resources are scarce. The good news is that metal can be recycled limitlessly. In the article “Peak Metals: Metals Recycling Generates Green Jobs and Cuts CO2 emissions, written by Joyce Nelson, she discusses the positives of recycling and worries.

Where does aluminum come from; how is it made, discuss the history of aluminum and how it compares to other material. When did the use or application of aluminum become popular? Explain the circumstances or preceding events associated with popularity.

This purpose of this experiment is to calculate the thickness of a sheet of aluminum foil. This experiment is necessary because the human eye cannot accurately measure the small thickness of aluminum foil with only a ruler. However, to understand the procedure one needs to understand conversion, density, and volume. Conversion is when one converts one unit to another unit using a conversion factor(e.g. 2.54cm/in). Density is how much mass there is in a certain volume(density=mass/volume) and it stays constant in a substances and mixtures that have the same composition. Volume is the amount of space that an object occupies. The experiment will consist of weighing of aluminum foil, measuring the length and width, then converting these values

2092 grams, which once the initial mass of the watch glass was subtracted than the weight of the crystals was recorded: 15.6421 grams. Results: The following chemical equations highlight the changes that the original aluminum went through: 1. 2 Al(s) + 2 KOH(aq) + 6 H2O(l) →2 KAl(OH)4 (aq) + 3 H2 (g) 2.

2. Obtain an evaporating dish and carefully weigh it to the nearest 0.01g on top of the loading scale and record its mass on the data sheet.

Aluminum recycling is the process by which scrap aluminum is reprocessed to be used in products after its initial production. Aluminum producers and recyclers in the aluminum industry work with individuals, businesses, and communities to enable both curbside and industrial recycling programs. For most aluminum products, the metal is not consumed during the products lifetime, but it is simply used making it easy to recycle without losing its intrinsic properties. Used beverage container (UBC) recycling is the most recognized of the aluminum recycling programs. However, end of life recycling of certain products like building parts and cars allows for the production of recycled materials like window frames, wire, tubing and electronic parts. The following is step by step process of aluminum recycling:
