Acetic acid

β-D-Glucose Pentaacetate from its Original D-Glucose and it comparison with literature though Melting point, TLC, IR, 1H and 13C NMR Abstract: The synthesis of the product: β-D-glucose pentaacetate is done though the acetylation using acetic anhydride with D-glucose with the help of sodium acetate. The recrystallization of the product is done though a polar solvent like water. The Result of this experiment has a percentage yield of 61% and analytical methods that are to detect the products

Throughout the course of this Investigation, how sugar influences the rate of fermentation and how this in turn, affects the overall quality of wine was explored. Three wines were produced, each with varying sugar levels. The Investigation was designed so that one wine had a fairly low sugar content; one had an ideal sugar content and one had a high sugar content. After the fermentation process stopped, a taste test was conducted in order to assess the quality of the wine. The taste testers were

-cyclooctene with air. Under our experimental conditions, the con- version of cis -cyclooctene can be arranged in the ascending order of tol- uene (0.9 mol%) b dioxane (2.6 mol%) b DMA (30.6 mol%) b acetic acid (49.2 mol%) b DMF (61.2 mol%), inconsistentwiththe risingorder of the epoxide selectivity: acetic acid (72.2%) b dioxane (86.9%) b DMF (98.8%) b toluene (100%) = DMA (100%). The solvent plays an impor- tant role in the epoxidation reactions, similar to the reports in the literature [23,25] . DMF

from the common cold and the flu (2014, Organic Information Services, Health benefits of baking soda). Vinegar is an acid around 2-3 on the pH scale (it is a pretty weak acid). It can also be called CH3COOH (Science Buddies, 2002 – 2014). The pH scale measures if something is an acid or a base and determines how acidic or basic the substance is. Its main components are acetic acid and water. Vinegar is used to preserve foods and is also used as a condiment on many foods, such as salad dressing. Vinegar

Arabidopsis thaliana is used. Its cell suspension is cultured weekly by tenfold dilution. It contains 100ml fresh growth medium, 4.3g/L Murashige and Skoog basal salt mixture which is the mixture of ferrous sulfate heptahydrate, naphthaleneacetic acid, and kinetin. The salt mixture is then adjusted to its optimum pH. Cell cultures are incubated at 23C where the light and dark intensity are controlled. For this experiment, 16 hours of light and 8 hours of dark. Filter sterilized cadmium (Cd) chloride

There are many unique compounds that can be synthesized using methods of chemistry that are serve as biological importance in the human body. Porphyrins are an example of one of these compounds and it helps create many substances utilized by the body, like hemoglobin (National Library of Medicine, 2013). Porphyrin, when it is in its purified form, can be mixed with several metals to form metalloporphyrins, for example if magnesium s the metal mixed with the porphyrin it can create chlorophyll (Weldegirma

Preparing Esters by esterification method using carboxylic acid to an alcohol, which is 1.0 ml of ethanoic acid to the ethanol, and ethanoic acid to the propan-1-ol, also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound, famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester, which was known of its smell. However it was expected to have a pleasant smell

Rose Dopkin 10/18/2014 Period 7 Eggs to Model Osmosis Experiment Team Members: Rose Dopkin, Solomon Alhakeem, and Kelly Kinsella Problem: What effect does submerging an egg in substances with different concentrations have on the mass of an egg? Variables: Independent Variable: substance egg is soaked in Dependent Variable: mass of egg (in grams) Constant Variables: temperature of location, length of time egg is soaked for, amount of light received, same type of egg, Experimental Control: The

As previously said, the experiment was about finding out chemical components in Tylenol and Anacin, the task was to find which of those compound contains acetaminophen and acetylsalicylic acid. Two tablet of Tylenol and Anacin were given and crushed in two different mortar and pestle in order to avoid cross contamination. When taking a sample of both compound out of mortar, two very clean spatula were used to put the powder in the test tube and then added 2.5 ml in each test tube of 50/50 mixture
