The sample will be passed through a filter paper using a funnel‚ after being boiled on a hot plate in a fume hood and dissolved in a solution of potassium hydroxide to remove the impurities. By adding an excess of sulfuric acid and cooling the solution in an ice bath‚ the technique of vacuum filtration using a Buchner funnel will be employed‚ crystals of the hydrated aluminum potassium sulfate salt will yield and these will be collected. Methanol will be used to rinse

green house gasses and work towards heating the Earth’s surface temperature. Sulfuric gasses affect climate in more complicated ways which is mainly a function of the concentrations of these gasses in the atmosphere (Ward 2009). This paper will examine the role volcanic eruptions have in affecting climate through the ejection of volcanic ash and the emission of different volcanic gasses including CO2‚ H2O vapour‚ and sulfuric compounds‚ and the impact certain historic volcanoes have had on climate by

We then prepared the nitrating solution by mixing 0.75 mL of concentrated sulfuric acid and 0.75 mL of concentrated nitric acid. We then mixed the two solutions‚ the mixture of sulfuric acid and nitric acid to the mixture of methyl benzoate and sulfuric acid. When the nitrating solution was being added to the mixture o of methyl benzoate and concentrated sulfuric acid. There was a color change. The color change was from clear to light yellow. As we added more of the mixture

ABSTRACT: The electrophilic aromatic substitution reaction is the attack of a benzene ring on an electrophilic species resulting in the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl

Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of

Laboratory; John R. Ganson Ph. D‚ Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol‚ to a better leaving group. In order for this reaction to synthesis 1-Bromobutane‚ four major methods refluxing‚ simple distillation‚ separation‚ and gravity filtration needs

product is washed with sulfuric acid‚ water‚ and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with sodium bromide and sulfuric acid. The sodium bromide reacts with sulfuric acid to produce hydrobromic acid . Excess sulfuric acid acts to shift the equilibrium and speed up the reaction by producing a higher concentration of hydrobromic acid. The sulfuric acid protonates the hydroxyl

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can
