INTRODUCTION Lactic Acid is an organic compound with the formula CH3CH (OH) COOH. Lactic is one of the types of fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final

Cause and Effect Essay: Acid Rain Pisal Sorn Advanced Writing Skills - ELT 114 Section 1 Professor: Robert Flinn April 11‚ 2014 Cause and Effect Essay: Acid Rain Acid rain is a rain or any other form of precipitation that unusually acidic‚ meaning that the level of pH is below 7. Acid rains can happen due to the emission of sulfur dioxide and nitrogen oxide‚ which it reach to water molecules in the atmosphere to form acids. Acid rain is resulting from natural

Benzoic Acid and Benzoates in Food‚ Drinks and Medicines Benzoic acid and benzoates are common additives to food‚ drinks‚ medicines and cosmetics‚ and they also occur naturally in many plants. They are useful chemicals in manufactured products because they kill or inhibit both bacteria and fungi and can act as preservatives. Benzoic acid and benzoates are considered to be safe chemicals for humans when they’re used in small quantities‚ but there are at least two situations in which even small

Introduction: In this lab‚ we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform‚ it consisted of adding a small amount of one of the organic compounds to a well‚ and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid‚ benzoic acid‚ benzyl alcohol‚ benzylamine‚ p-cresol‚ and p-toluidine. My initial hypothesis about the acidity/basicity
