Exploring the acid content of Pepsi products Lab performed: February 27‚ 2012‚ March 12‚ 2012‚ and March 19‚ 2012 Purpose: The purpose of this experiment was to discover the unknown concentration of acid in six different Pepsi products; Pepsi‚ Diet Pepsi‚ Dr. Pepper‚ Diet Dr. Pepper‚ Pepsi Wild Cherry‚ and Pepsi Max. Titrations find the point at which equal moles of a known concentration react with equal moles of an unknown concentration giving the equivalence point. Also‚ the

be used in order to determine the reaction stoichiometry Magnesium is used to react with hydrochloric acid in order to produce hydrogen gas. One of the purposes of this experiment is to determine X in the equation below The mass of the magnesium used is measured before the use in the experiment via an analytical balance. The known amount of magnesium is then reacted with excess hydrochloric acid which causes the magnesium to be the limiting agent in this particular reaction. The amount of HCl used

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

ACID BASE IMBALENCE INTRODUCTION The body normally maintains a steady balance between acids‚ produced during metabolism and bases that neutralize and promote the excretion of the acids.Many health problems may lead to acid base imbalance.Patients with Diabetis mellitus ‚COPD‚and kidney disease frequently frequently develop acid base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for

“nature of teaching” hypothesis states how difficult it is to evaluate a teacher. This hypothesis shows that the likelihood of merit pay working in public school very inconceivable‚ do to all the other factors that affect public school curriculum‚ like focusing on a topic for longer then the curriculum states should spent on a topic. On the contrary the ”political cost” hypothesis insists that there is nothing ingrained in teaching that makes merit pay not work. The hypothesis uses the statistics

The discovery of Otzi had scientists estimating how old the mummy was and what types of minerals his tools were. One hypothesis was that the ice mummy lived around 2000 BC because his tools‚ especially the ax head‚ which looked to have contain bronze and bronze was mostly used in tools and such in 2000 BC. To find the answer to the questions‚ and to see if their hypothesis were

the most known around the world‚ but it very important to me and the world. No one knows what really causes MS‚ but scientists have many hypothesis of how the disease is caused. There are 4 main hypothesis’. Immunologic is one cause some scientists believe to be true where the immune system malfunctions and starts eating away the myelin sheath. Another hypothesis for why MS is caused is environmental. Through pattern‚ people that live near the equator have less MS and if they had MS they usually lived

In this report‚ I will explain what Sulfuric Acid is‚ the health risks and hazards associated with it‚ the safety precautions that should be taken and how the spill should be handled. Sulfuric Acid‚ H2SO4‚ also commonly known as battery acid or vitriol‚ is one of the top products in the chemical industry‚ with 40 million tons produced annually in the U.S. It is a colourless‚ odourless and oily mineral acid that is soluble

Hypothesis Statement Trees that exhibit gumming are more resistant to fusarium dieback caused by the polyphagous shot hole borer (PSHB) because the gum secreted acts as a defense against beetles that attempt to penetrate the bark‚ and as a result grant the tree faux resistance to the Fusarium euwallaceae fungi. Introduction Californian agriculture is at great risk because of a disease being spread by the Polyphagous Shot Hole Borer (PSHB)‚ Euwallacea sp. The PSHB is an ambrosia beetle
