properly appreciate the importance of aluminum recycling in our world, an aluminum recycling experiment was done through alum synthesis. The process by which this was done recycled solid aluminum can pieces (Al) into the form of solid raw alum crystals (KAl(SO4)2) through a series of reactions. Application of this experiment comes from analyzing the calculated percent yield of alum crystals, understanding where error is involved, and determining how a perfect yield could be obtained. First, 0.9-1.2

Dangerous hair products In recent years, many people are choosing natural products for hair and skin care. The main reason for that is the fact these products are full of chemicals and harmful toxins that may have a negative impact on the health. Many researches and studies have shown that nutrition is very important, but it is not the only way how the toxins and chemicals can get into the bodies. Another option that is often completely disregarded, is by regularly using and applying certain products

Alum Whithey discusses the cultural changes and background of facial hair in his essay “Facial Hair and Masculinity in the Eighteenth Century”. Using facial hair as a reference, Whithey describes the changes in the cultural definition of 'masculinity'. In the early eighteen hundreds, having a beard showed that a man was fertile and virile. Changes in medical knowledge led to the belief that beards were 'uncouth' and using the 'humors' theory of medicine, removing stubble “...was therefore to rid

After interviewing Jeff Karlson a Brown University “Whiskey” Fraternity Alum and Garrett Wassom a pledge of Chi Phi at Cu Boulder, the differences between the times showed. The questioned the two were asked was “Did you or have you experienced rape on or associated with your fraternity?” the reply from Jeff was “Fraternities’

lab, my lab group was able to test and verify all the parts of alum through a series of tests. We also were able to conclude whether or not the substance was alum after all. The testing of the alum, AlK(SO4)2, was able to conclude the melting point of alum, to determine whether sulfate was present in alum, and the water of hydration in the alum crystals. The melting point of alum was measured to be 92.5℃. This was tested by taking the alum and crushing it into a powder which was put into a capillary

useful product. In this experiment, aluminum is converted into potassium aluminum sulfate, or what the paper will now refer to as “alum” in order to see how much of the can is recyclable. The purpose of the abstract will be to go over the process of producing alum, writing net ionic equations for each step in the production of alum, and calculating the percent yield of alum. Materials and Methods The first step was adding 1.1013 g of aluminum can pieces to a 250. mL beaker. The same beaker was then

By adding theoretical dose of alum which was 6.55mg of alum, 4.9% of phosphate was removed. However, by adding pragmatic dose of alum which was 20mg of alum, 86% of phosphate was removed. This was because that the equilibrium the equation, Al³⁺ + HₐPO₄³⁻ ͣ ⇌ AlPO₄ + aH⁺ showed that when excess Al³⁺ was added, then the reaction went forward which would make more products of AlPO₄ + aH⁺. Therefore, by adding pragmatic dose of alum of 200mg/L produced more precipitate of AlPO₄ which

Introduction: A crystal is a solid whose atoms are arranged in a specific repeating pattern. Real crystals undergo years to grow, but today's scientists have obtained a way to grow crystals right in the lab. They have also been effective in finding a way for people who aren’t scientists to grow crystals in the comfort of our own home. Although they may not be the same crystals we wear as jewelry, they give us a basic idea of the unique types of crystals that are made, formed and grown all over the

Introduction Aluminum is a significant good in modern society due to its many uses in commercial goods. Because aluminum is consumed so rapidly, it becomes somewhat expensive to extract it from its original source. In recent years, there has been a push toward the recycling of aluminum through electrolytic reactions resulting in significant decreases in cost and aluminum production. Materials and Methods Using a scoopula 1.2141 grams of aluminum can pieces were weighted on an analytical balance

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

It is an honor to accept this award. I would like to thank Dr. Stroble, Dr. Shuster and the alumni leadership team for their continued support for the Alumni Association both here and abroad. I would also like to thank my husband, Mike, that is here with me tonight. He was a true advocate for me while I was pursuing my education goals and he continues to serve as a volunteer for Webster University. I thank you. My experience with Webster University began in 2001 as I made the decision to pursue

metal compound. The example of mordant that usually used in dyeing textiles are alum, iron, tin, blue vitriol, and tannic acid. However, alum is one of the most effective mordant and fairly non-toxic. Alum (potassium aluminium sulphate) is the most common mordant. It does not effect the colour. To helps evenness and brightens, it is usually work out together with cream of tartar. The common ration is 85 gram of alum and 28 gram of cream of tartar. Iron (ferrous sulphate) is called copperas. It will

Fifty tonnes of shale yielded one ton of alum, and left behind vast quarries and spoil heaps which are still visible on the hillside. The primary uses for alum were as a fixative for dyes and for softening leather during the tanning process. One of the critical ingredients used in its production was human urine! Evidently, most natural deodorants contain alum, which prevents the growth of bacteriaand eliminates the odour related to sweat; fortunately

Top 15 Home Remedies for Foot Odor Did you realize that our feet have 250,000 sweat organs! What's more, that they create around 250 ml of sweat every day! Isn't that a lot of sweat enough to give you foot smell? Truth be told, you may sweat all the more paying little respect to temperature or climate and if you have more motivations to get sweat-soaked feet because of hormonal changes occurring in your body. 1. Heating Soda Foot Bath to Control Odor Sweating is by all account not the only explanation

game plan from first-year understudies through doctoral-level contenders; the Bothell and Tacoma grounds, recognition adding to a trademark character and limit stimulated advancement, action assembled activities to upper-division understudies and to alum understudies. The fundamental mission of the University of Washington is the protecting, progress, and TV of learning. The University jam limit through

INTRODUCTION Purified water is essential for living a healthy life as such everyone should have access to it. Drinking water conditions have great impacts on people especially in the rural and remote areas where access to safe drinking water is very important. Drinking untreated water may cause to fatal diseases. Statistics shows that these diseases resulted in ninety percent of all deaths of children under five years old in developing countries, due to low immunization of children to infection.

Cons: If we are required to grant access to ‘left-field’ students, is there any guarantee of additional payoff. ‘…in my opinion these variables are less relevant than the fact that on the margin the black Harvard alum will make so much more difference to the world than the white Harvard alum.’ - Jennifer Hochschild. A statement as bluntly severe as this simply cannot be for any person to assume. No individual is to know whether or not they can be of more use to the world than another; that is a bare-boned

In particular, we talked about the first Spelman alum to go to medical school. This Spelman alum was named Georgia Dwelle. During her career, Dr. Dwelle achieved many accomplishments. In 1904, she graduated with honors from Meharry Medical School. Then in 1920 Dr. Dwelle established Georgia’s first hospital for African American
