Acid Rain Acid rain, to our eyes, is not much different from regular rain, but the contents of that precipitation can be devastating to plant-life and ecosystems. Acid rain is formed in the atmosphere when gases such as sulfur dioxide

Synthesis and Purification of Acetylsalicylic Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions, creating an ester either with the hydroxyl or with

Litmus, what is it? And why is it important? Litmus was first used around 1300 AD by Arnaldus de Villa Nova, a Spanish alchemist . The word Litmus, comes from the Norse word, meaning ‘to dye, or color’ . Litmus

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

Chapter I Background of the Study Chemical compounds can be classified as acidic, basic, or neutral substances based on several conditions. One factor considered is the color reaction which can be observed through the use of indicators. An indicator is

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which

The Br–Br bond becomes polarized and the more positively charged Br atom is transferred to the alkene to yield a bromonium ion and a bromonium anion. The bromonium anion attacks a carbon atom to open the three-membered ring and produce

Acidification also occurs when base cations such as calcium, magnesium, potassium and sodium are leached from the soil. This leaching increases with increasing precipitation. Plants take bases from the soil as they grow, donating a proton in exchange for each

Once this precipitate is separated by vacuum filtration the melting point helps identify the product. Laboratory notebook reference: Pages 9-10 Chemical Reactions: [pic] Observations: The experiment was begun by mixing trans-cinnamic acid and glacial acetic acid with an added stir

An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a
