Eichbauer IB Chemistry II – Period 6 16 February 2015 Investigation of the Effects of Acid Rain Background Information Acid rain is when there is a mix of wet and dry deposited material in the atmosphere that have higher levels of nitric and sulfuring acid. These chemicals formed can be from natural causes‚ like volcanoes and the decay of vegetation‚ or man made causes like fossil fuel combustion. Acid rain can be measured using the pH scale‚ and will always be on the lower end of the spectrum

First of which involves removing all of the flesh from the hide‚ once this is complete the hide goes into a solution known as the pickling processes. Once to this stage there are several products that may be used in order to complete a pickled fur. There are three main components to creating a pickling solution; these consist of sulfuric acid‚ non-iodized salt‚

Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order to create the powder form of aspirin

MANUFACTURE OF SULPHURIC ACID IN INDUSTRY 1. Contact process produces more than 90% of the world’s sulphuric acid. 2. The raw materials used for the manufacture of sulphuric aced are sulphur‚ air and water. 3. The Contact process consists of three stages. a) Production of suphur dioxide b) Conversion of sulphur dioxide to sulphur trioxide. c) Production fo sulphuric acid 4. Stage I: Production of sulphur dioxide a) Sulphur is burnt in air to produce sulphur dioxide. S(s) + O2 (g)→SO (g) b) Burning

Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point
