Aluminum Synthesis Lab Report

Introduction: In the world, there are a lot of important materials that we use in our everyday lives. Aluminum is a major metal that has many uses and is very helpful in achieving things through the use of recycling. The purpose of this experiment was to show how aluminum undergoes many chemical reactions to produce Alum.
Materials and Methods: When this recycling experiment was conducted, we first had to gather the essential material needed. Once the material was acquired, 1.0094 grams of Aluminum were weighed and then transferred to a 250mL beaker. The 250mL beaker continued to remain in use for the next few steps. 1.4M KOH solution was added to the Aluminum sample that was previously obtained. For gas to escape the lab, there was a fume

With background knowledge of chemistry, it is known that aluminum also has a molecular weight of 26.981 g/mol, which then lead to the reaction of 0.0374mol of aluminum. The first reactant was a redox reaction, formed through aluminum, adding potassium hydroxide and water to yield potassium aluminum hydroxide, plus hydrogen. During the process of this reaction, there was many changes occurring. The color of the reaction turned grey at first then eventually turned black. The solution was also evaporating due to the use of the fume solution. As the compound was reacting, the aluminum pieces were also dissolving, with only a few pieces left inside. The process of the second reaction included the adding of a new substance which consisted of sulfuric acid. The sulfuric acid along with potassium aluminum hydroxide, was yielded to produce aluminum hydroxide, potassium sulfate, and water. This reaction was both a precipitation reaction and an acid-base reaction. Once the sulfuric acid was added, the reaction became very chunky. With the use of a stirring rod, the substance went back to liquid formation. The color also turned white, as if it were milk. The solution also looked foggy, so it had to be filtered yet
