Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

The result of the total plate count of Adlay vinegar fortified with iron in different concentrations was shown in Table 13. The analysis was performed using 1:100 dilution in triplicates and the data gathered substantially varies. The differences could be explained by the fermentation temperature‚ and other environmental conditions of the samples. Since the fermentation of the samples were done in uncontrolled environmental conditions. According to the study of Millet and Lonvaud-Funel (2000)‚ the

catalyst. The percent yield of the product was sub-par. It was found to be 54.4%‚ which may have been due to the formation of other byproducts during the experiment. For example‚ the benzoin and copper(II) acetate mixed with ammonium nitrate and acetic acid could have caused the copper(II) acetate to not fully react with the benzoin. This side-reaction led to less benzoin intermediate which in turn led to a less yield of benzil product. Additionally‚ the melting points found were similar to that of

AGAROSE GEL ELECTROPHORESIS Gel electrophoresis is a widely used technique for the analysis of nucleic acids and proteins. Most every molecular biology research laboratory routinely uses agarose gel electrophoresis for the preparation and analysis of DNA. We will be using agarose gel electrophoresis to determine the presence and size of PCR products. Background: Electrophoresis is a method of separating substances based on the rate of movement while under the influence of an electric field

with no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has: vinegar. The acetic acid inside the vinegar strips the shell‚ calcium carbonate‚ away from the egg‚ the chemical formula is: CaCO3 (s) + 2 HC2H3O2 (aq)→Ca(C2H3O2)2 (aq) + H2O (l) + CO2 (g) (Imagination Toledo‚ 2017) Once the egg has been separated from its shell‚ the only

The TLC plate was put into a developing chamber containing 200:1 acetic acid and allowed to developed until the solvent reached almost to the top of the TLC plate‚ which took about 10 minutes. When the TLC plate finished developing‚ I observed the plate under UV light and noticed that the salicylamide was the only

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

The purpose of this experiment is to synthesize 1‚ 4-Di-t-butyl-2‚ 5 – dimethoxybenzene via the Friedel-Crafts alkylation mechanism by reacting 1‚ 4 – dimethoxybenzene with tertiary-butyl alcohol in the presence of sulfuric acid as a Lewis acid catalyst‚ and involves the attack of the aryl group at the electrophilic trimethylcarbocation. The resulting product will be recrystallized using methanol and characterized using TLC and melting point analysis. Materials: 400-mL beaker‚ ice
