Abstract The purpose for this lab was to use aluminum from a soda can to form a chemical compound known as hydrated potassium aluminum sulfate. In the lab aluminum waste were dissolved in KOH or potassium sulfide to form a complex alum. The solution was then filtered through gravity filtration to remove any solid material. 25 mLs of sulfuric acid was then added while gently boiling the solution resulting in crystals forming after cooling in an ice bath. The product was then collected and filter through
Chemistry students. Major concepts for the “Analysis of Alum” laboratory are percent composition, water of hydration, and molecular formula. They will be used in three different experiments to determine the melting point of alum, the mole ratio of hydrated water to anhydrous alum, and percent of sulfate ion contained in alum. The values acquired in the lab should be close to the calculated values of 92.5 ˚F, 12 moles of water to 1 mole of alum, and 59%, respectively. Before beginning the experiment
The Synthesis of Alum from Aluminum lab centralized on the creation of potassium aluminum sulfate dodecahydrate from a set amount of aluminum, and using quantitative analysis to then compare the actual yield to the theoretical yield. The synthesis of alum was conducted through a series of steps involving aluminum foil, potassium hydroxide, and sulfuric acid. Given that aluminum is amphoteric, meaning it can dissolve in both strong acids and strong bases, potassium hydroxide and sulfuric acid were
As humans, after a long day of activity in our busy lives, we tend to sweat. From going to the gym, walking around, and just weather in general, we all have a habit of sweating. Applying deodorant after a morning shower or when we begin to get sweaty or clammy has become second nature for to of us. Coming in many forms such as roll ons, bars, and sprays, deodorant is used to control the production of sweat and underarm odor. As human nature has evolved we have become more conscious about our body
Objective: Making alum called potassium aluminum sulfate dodechydrate, from aluminum and potassium hydroxide. Materials: Aluminum foil weighing 1.0254 g ripped into small pieces, 250 mL beaker, Buchner funnel, filter paper, graduated cylinder, 25 Ml of 3 MKOH solution, Stirring rod, 35 Ml of sulfuric acid, 50 Ml of Aqueous ethanol solution. Procedure: we started this experiment by gathering aluminum foil, in the lab manual it does not clearly state how small the piece of foil need to be, so we cut
Testing the Suitability of Using Alum Synthesis as a Method of Recycling Aluminum Introduction: According to The Aluminum Association, “Americans throw away nearly $1 billion worth of aluminum cans every year” (The Aluminum Association,2014). With the increasing number of aluminum cans being disposed of in landfills annually, it is important to investigate ways to cut back on waste and how these products can be recycled in the most efficient way possible. The purpose of the lab was to further
my diploma and my ears buzzed from my cheering family members. Without knowing this experience would change me forever. It then hit me, four years had finally come to an end. I was now a high school graduate. I felt no particle way about it being an alum. All I could think was, it was probably the last time I would see 90 percent of the people again. Even though it didn’t bother me none. The majority of students were unsure of their future aspirations while others beamed with excitement. The morning
Virginia Tech Alum was a once in a lifetime opportunity. The chance to meet with a Virginia Tech Alum to help model the plans I will make to become successful was an opportunity that I’m very thankful for and will never forget. Thanks to the insights of my research and guidance received from the alumni I met with, I intend to approach my next five years in the Pamplin College of Business in a much more organized and determined manner. Surprisingly, I was able to meet with an alum that was somewhat
removal rate reaches to 98.9% and a slight total nitrogen removal about 29.9%. On the other hand, Xu et al. (2009) investigated effect of the recovered alum from water treatment sludge in CEPT of sewage as a coagulant. The obtained results reveal that pollutants removal efficiencies form CEPT using the recovered alum are similar to that of the fresh alum. Removal efficiencies of COD and turbidity reach up to 53% and 96% respectively with the recovered
The treatment of surface wastewater is aimed at bringing contaminated water back to its previous state for domestic use or otherwise. Some of the sources of wastewater include industrial effluents from manufactures, agricultural effluents, agro-industrial as well as domestic wastewater from sinks, bathtubs, toilets, and so on. Particles in the water from the various sources include bacteria, organic matters, and sand which cause the water to be turbid or discoloured in appearance and have an unpleasant
The Homewood Grounds, amidst adjacent to the complete continuity of Charles Town, is the key justification for understudies, and three included grounds house alum schools. Hopkins aswell has three included reason for its School of Cutting edge Worldwide Studies (SAIS) in Washington, D.C.; Bologna, Italy; and Nanjing, China. The Hopkins Blue Jays try in the NCAA Division III Centennial Gathering, in any case
is being used for preventing human papillomavirus (HPV) and hepatitis B virus (HBV) infections. A combination adjuvant of MPLA with alum (AS04) used for HPV vaccination has been shown to be effective compared to administration of only alum along with antigen.16 The AS04 was shown to enhance humoral and B-cell immunity as well as produced antibody titers faster than alum.17 A number of studies consisting use of TLR adjuvants either alone or in combination with other immunoadjuvant are underway to explore
Alternative medicines are widely used around the world and are becoming more controversial each day. Alternative medicines are considered in the eyes of some doctors as “junk science”. Not only do they see the medicines as “junk science” but they also fear that the medicines can potentially be very dangerous. “Junk science” according to junkscience.com is “faulty scientific data and analysis used to advance special interests and hidden agendas”. In other words, “junk science” practicing or studying
The system of Affirmative Action’s role in college admissions needs to change, because although it has assisted many minorities in their pursuit of higher education, it has also put others, non-minorities, at a disadvantage. College admissions should focus on the merit, academics, and character of a potential student rather than the specific attribute they can’t change – their race. One problem that exists with Affirmative Action is that it can actually be hard on minorities, whom the system was
In the novel The Disreputable History of Frankie Landau-Banks, the salad bar prank was mean spirited and an embarrassing to the Alabaster. The salad bar prank was a prank planned by Frankie, but executed by the Basset Hounds, a secret all male society on campus. However, the Basset Hounds are under the impression their leader, Alpha, is planning the pranks, when in reality Frankie is. Before the salad bar prank, she was the mastermind behind the library lady prank, doggies in the window prank, and
I would like to take this opportunity to thank the Admissions Office for reconsidering me for admission at Mount Holyoke College, and even though I am waitlisted, MHC remains my first and foremost choice and the fact that it is my dream school remains unchanged. Thus, if extended an offer, I would ecstatically accept it. Being part of a diverse and empowered community of women at Mount Holyoke will give me a voice and a strong, multifaceted identity. This is essential for me as I am the first

For next semester I will make it my goal for them to not feel like everything is on their shoulders. I want this chair to know that I am here to help in anyway shape or form because I know new policy changes are tough for people to understand. Risk Management: This is a very important chair because
My Great Smoky Mountain Vacation The Great Smoky Mountains is a wonderful place to have a family vacation because of the beautiful log cabins, the downtown city life, and the historic hiking trail Alum Cave. The Great Smoky Mountains is located in Gatlinburg Tennessee. It’s named after its beautiful blue-like smoky mist that covers the mountains. It’s made up of over 500,000 acres of southern Appalachian wilderness. It’s the largest tourist park. The Great Smoky Mountains itself is absolutely breathtaking
Dark underarms or armpits are a condition of the skin under the arms that becomes dark. It becomes a major concern to fair skin people as dark armpits are more visible on fair skin than on dark skin. The causes for dark underarms are: • Improper cleaning • Sweating • Friction due to different types of clothes • Dead skin cells • Use of shaving products • Deodorants containing alcohol The symptoms of dark underarms are • Sweating • Itching • Dark skin along the area of armpits • Bad
A powerful thing occurs when a leader applies the theories of behavioral science; they possess the ability to directly influence the behaviors of their employees. In other words, a leader’s success is defined as their ability to get things done, and is an integral component for creating a positive and engaged workforce ("Applied Behavioral Science | CLG, Continuous Learning Group," n.d.). In Unlock behaviors unleash profits, the author discusses a case study where a leader unwittingly tapped into
