Sulfuric acid

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

(a) When dry pH paper was placed over household ammonia, the paper quickly turned a dark blue, indicating that it was a base. (b) When moist pH paper was placed over household ammonia, the paper turned dark blue faster than when dry, still indicating that it was a base. (c) When pH paper was placed over bleach, the paper turned blue, which indicated that it was a base. (d) When pH paper was over ammonium carbonate, the paper turned dark blue even faster than the moist paper over household ammonia

In this experiment, we alkylated P-dimethoxybenzene using tert-butanol and sulfuric acid in order to find the major product of the reaction. Through this experiment, we obtained about 390.2 mg product which equates to about 88.85 percent yield. This yield is very high, even in comparison to alkylations conducted by other undergraduate students such as Jonathan Melville who had a yield of 62% (1). Furthermore, the melting range was 76-85°C, differing from the reference melting point of 102-104°C by

Upon entering the village of DePue, IL, one may ponder about the festering odor of sulfuric acid in the air that clashes with the scenic view of a serene lake surrounded by wooded land. The main street of DePue is lined with locally owned businesses, along with abandoned, crumbling buildings. The community members of this village may either smile and wave at a passer-by, or glare at you with an off-putting facial expression. Despite the confusing impression a non-resident or visitor might form, DePue

After going through multiple reactions with nitric acid, sodium hydroxide, heat, sulfuric acid, and magnesium, the metallic copper was regenerated. The starting 0.021g of copper changed from solid to liquid to solid to liquid, and finally ended at a solid state. The original copper was 0.021g and the ending copper was 0.008g creating a 38.10% recovery. Results + Calculations: During the lab the staring copper reacted with 10 drops of nitric acid, creating a dark green liquid. Distilled water was

will be explaining the use of ‘superphosphate’ in our local community and how it helps in the process of fertilising. The fertiliser made by using local rock containing fluorapatite( referenced from instruction sheet ) which is combined with sulphuric acid resulting in the solution of ‘superphosphate’ being formed. Also we will be discussing how ‘superphosphate’ affects the community and the environment surrounding it, alongside how is produced and the by-products formed and the effects of these by-products

Acidic Environment Oxides of non-metals which act as acids Non-metals burn in air or oxygen to produce acidic oxides. The addition of water to soluble oxides produces acidic solutions. Oxides of non-metals which act as acids include: * Carbon reacts with oxygen when burnt to form carbon dioxide which is acidic in nature. When dissolved in water, it becomes H2CO3 (carbonic acid). CO2 (g) + H2O (l) →H2CO3 (aq) * Sulfur burns in oxygen to

irritation and organ toxicity (Ethanol). This compound is combustible. Some hazards of working with nitric acid are its toxicity and the irritations associated with inhalation, ingestion or contact with its vapors to the skin and eyes (NITRIC ACID). This compound is not combustible. Some hazards of working with sulfuric acid are serious burns and damage to the eyes, skin, and organs (sulfuric acid). This compound is not combustible. Some hazards of working with methyl benzoate are eyes, nose, throat

In the final part of phase one which was steps 9-11, five different metals were placed in Hydrochloric acid. The five metals were copper, magnesium, lead, iron and zinc. Magnesium was the first to react and it created bubbles before it completely dissolved in the acid. Zinc was extremely reactive and produced a lot of bubbles. Iron started reacting after zinc and created some bubbles. Then slowly lead had produced a few bubbles and
