Acid-base chemistry

What is a Periodic Table and what is it used for in science and our everyday lives? On entering the chemistry laboratory at Mercer University, for Science 100 a large colorful chart displaying rows and columns of cells, was hanging over the chalkboard. I immediately felt a bit intimidated and my heart began racing. I questioned myself as to what am I about to experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and…

The reagent phenylmagnesium bromide is then added with benzophenone and a magnesium salt precipitate forms. Finally the salt is converted into triphenylmethanol by adding water, and acid is added to dissolve any basic product. Grignard Reagents are also used in the following important reactions: Grignard reagent can be added in excess to an ester or lactone to give a tertiary alcohol in which two alkyl groups are the same, and the…

around eight, or in other words the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The combination of a weak acid and a strong base would result in an endpoint that corresponds to the range of phenolphthalein indicator approximately a pH of eight. Image A Phenolphthalein is composed of C14H20O4, as shown in…

This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end…

light gray color and the strips of zinc added to solution were approximately 5 cm. When zinc was tested with water there were no noticeable characteristics of a reaction occurring, such as bubbling or a color change. When zinc was added to the weak acid H2SO4, at first there was no noticeable reaction, however,…

and even cars (webprojects.edu, 1). Acid rain is something humans should be concerned about in the twenty-first century due to our advancements in technology. The majority of the United States suffer from acid rain and as a result, many communities are impacted making water unsuitable for drinking and the environment around them damaged. Despite the fact that many people think acid rain isn’t a big threat to the world, damages caused by acid rain can be…

contains is held together by one thing: chemistry. Chemistry plays an important role in all of our lives due to this fact. Whether in my career or in everyday events, chemistry will be an unseen, yet central, influence in my life. This is apparent in both my personal activities when baking, wearing clothing, participation in holiday traditions and my professional life when writing software, creating biological implants, engaging in computational chemistry and in the creation of the hardware I…

Adding sodium bromide and sulfuric acid had visible effect on the yield of the reaction. In this experiment, excess NaBr solid were removed due to having no important yield increase when more than 1.2 quantity of NaBr was used. Sulfuric acid was used in the experiment due to the conjugate base being very poor…

Synthesis of Schiff base Method preparation for Schiff base ligand is a straight forward synthesis and easily modified using different amines and carbonyl compound. This could be one of the reasons that make Schiff base ligand popular in coordination chemistry research. Synthesis of Schiff base ligand commonly, taking place in alcohol through condensation reaction of amines and carbonyl compound. The acid/base catalysis or heating is employed in the synthesis of Schiff base as their reactions…

color changes, precipitates, and gases. Those that did not have reactions were also useful in the deduction process. To fully understand how this elimination process works, one must have a better conceptual understanding of aqueous solutions, acid-base reactions, precipitates, and the solubility rules. An aqueous solution is any solution in which water is the solvent. Simply put, it dissolves in water. In order for a substance to dissolve in water, it must either match or exceed the strong…
