Phosphoric acid

Horssen CHMY 321 TA: Michael Giroux 10/31/17 Introduction: The purpose of this lab was to carry out a dehydration reaction of 2-methylcyclohexanol by heating it in the presence of phosphoric acid and determining which alkene product would be the major product. Methylcyclohexanols were dehydrated in an 85% phosphoric acid mixture to yield the minor and major alkene product by elimination reaction, specifically E1. The alkenes were distilled to separate the major and minor products and gas chromatography

Introduction The purpose of the “Cubatao Phosphoric Acid” company is production of phosphoric acid via hemi-dihydrate (HDH) wet process and sale of the products to various fertilizer manufacturing companies. Report summarizes description and mass balance of the process, investigation of economic and marketing issues, process and personal safety, social, economic and environmental sustainability of the process. Phosphoric acid, also known as orthophosphoric acid, is inorganic compound having chemical

Stoichiometric Reactions with Phosphoric Acid By Leah Herde Partner: Kayla Infante CHE 120-12 Instructor: David Chick   PURPOSE The purpose of this lab was to experiment with triprotic acid to create different salts through neutralization. Specifically, using varying volumes of sodium hydroxide with a constant 1 mL of 6M Phosphoric acid. In doing so one can examine the reactions and use stoichiometry to identify the products formed from the relationship between the reagents. INTRODUCTION Stoichiometry

3-methylcyclohexene is simple distillation where dehydration was used to prepare the final product. The results of the experiment showed that the 3-methylcyclohexene was formed via an E1 reaction from 2-methylcyclohexanol with a 1:1 ratio of sulfuric acid and phosphoric acid. However, some H2O was left over, which was seen when we look at the IR and see a small water peak. This could be due to the fact that not enough sodium sulfate was added and not for long enough. These results were confirmed by the quality

Hydrochloric Acid and Phosphoric Acid in an Unknown HCl – H3PO4 Mixture through Use of Potentiometric Titrations Andrea Byassee 8000 Utopia Parkway Department of Chemistry St. John’s University Jamaica, NY 11439 andrea.byassee12@stjohns.edu Report Prepared for: Quantitative Chemical Analysis Professor Neil Jespersen Due Date: October 16, 2014 Submitted Date: October 20, 2014 ABSTRACT The purpose of this experiment was to determine if soft drinks manufactured by Coca-Cola use phosphoric acid in their

We were assigned the ultimate task of finding the phosphoric acid in several rival sodas for this experiment but to get there it required many steps to be taken in advance. As we were a working for a major cola company it was crucial that we were aware of how to use the technology and then more importantly the relationships between all the findings we made through numerous experiments. Our main source of technology was a spectrophotometer so in order to move forward in finding anything out about

The goal of the lab was to discover the concentration of phosphate in various colas in order to help with a project for a major cola company. Before we could accomplish this final goal, a Spec 20 was used to test three colors of food colorings. A Spec 20 is an instrument used to “measure the intensity of a light beam before and after it passes through a sample and compares these two intensities” (What does a Spectronic 20 measure). The instrument is able to measure the percent transmittance and

(Guanine tri phosphate) etc. It’s a major constituent of cell membrane, nucleic acid, cellular energy transfer systems. Phosphates are essential for metabolic reactions releasing energy. It is required for encoding of the information in genes (as it is the component of nucleotides and nucleic acids). Are phosphates natural? Phosphate rock is mined from the earth. The rock is crushed and purified to form phosphoric acid, which may be reacted with caustic soda of lime to produce purified phosphate

for 5 days. However, bleach contains toxic gas which is harmful for organism as well; therefore, the solutions 2, 6, 8 were not the one lasted for the longest period when compared with other solutions. Fresh lemon juice Lemon juice contains citric acid and niacin, which enhance the water permeability of the gerbera’s stem and kill the germs effectively. Gerbera of solution 5 had the longest lifespan since the solution contained lemon juice that successfully killed the germs and helped improve the

(Territories). Coca Cola is one of the greatest customer related companies in Kenya, being one of the most preferred drink in Kenya and having the largest amount of customers. Coca colas main ingredients are caffeine, carbonated water, sweetener and phosphoric acid. The differentiation of inputs in the production of soda is very minimal as there is no alternative to the sugar NutraSweet which has been patented thus giving a supplier less power over a buyer. Suppliers of bottles are also dependent on the
