Acid

Benzoic acid, Benzocaine, and Fluorenone. Because the ratio is 1:1:1, that means all of the components are equally weighted in the total weight of the mixture. Since the starting weight of the 1:1:1 heterogeneous mixture was 0.618 g, you can assume that the 0.618 g is made up of the three components each weighing 0.206 g. This came from dividing the starting weight by 3, since there are three components. As shown in the percent recovery calculations above the percent recovery of benzoic acid was 60

INTRODUCTION 1. HISTORY AND GENERAL INFORMATION ON ADIPIC ACID 1. History on The Production Adipic acid is an important organic chemical raw material. In China, it is used as raw material in the production of Nylon 6/6 salt, polyurethane, plasticizers, high-grade lubricants and food additives. With the rapid growth of development, the application of adipic acid keeps expanding. The production of adipic acid is controlled in the hands of multinationals. An American chemical

Cinnamic acid was purified by hot filtration and recrystallized by a cold solvent. The solvent used in the experiment was water. Water is the ideal solvent for it has low solubility at low temperatures and high solubility at high temperatures. Cinnamic acid was obtained from the last lab. It was observed to be a white and flaky powder. The vial with the CA weighed and was 14.23g. From data collected from last week, the vial alone was 13.90g. Therefore, there was .33 g of CA (14.23-13.90g). The percent

INTRODUCTION Maleic acid and Fumaric acid are both compounds belonging to the carboxylic acids class. In this experiment, we formed the two isomers of 1,2-ethylenedicarboxylic acid and tested the solubility and melting points of both of these products. Both of these compounds involve a carbon-carbon double bond that is composed of one σ bond and one π bond. The overlap of sp2 hybrid orbitals forms the σ bond, and one empty p orbital forms the π bond. This process is illustrated in the figure below:

less diluted the acid is, the faster the ant-acid will dissolve. The results show this, as the ant-acid in the 0.5M acid took 9:02 minutes to dissolve; the ant-acid in the 1.0M acid took 2:50 minutes to dissolve and the ant-acid in the 2.0M acid took 2:09 minutes to dissolve. The trend of this experiment is the downward slope of the time when the acid becomes stronger, however, it is not as mathematically correct as the group had expected. The group had hypothesised that the 1.0M acid would take half

Acid Rain Introduction “Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal” (1). Rain is classified as acidic if it has a pH level under 5.7 (2). Acid rain is a growing issue in today’s society for a number of reasons. Acid rain’s effects mainly impact the air and environment. Aquatic life is significantly impacted

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 are oxidized; sulfur trioxide is converted into sulfuric acid by a chemical reaction with water, or when nitrogen dioxide reacts with hydroxide to form nitric acid. The most oxidation reactions are with ozone, hydrogen peroxide, and of course, oxygen. There are

cars. The term used to describe the problem is "acid rain". Acid rain has become a major environmental concern for several decades, it has broad economic, social and medical implications and has been called unseen plague of industrial age. The major components of acid rain is sulphur dioxide, sulphur trioxide, carbon dioxide and nitrogen dioxide dissolves in rain. These components deposited as dry and wet depositions. One obvious consequence of acid rain is corrosive effect on exposed stone and metal

scientific August Smith, just focus his studies on air in Manchester, England, he created a network of monitoring the quality of rain in northern Europe, where he recognized acid rain. During the last ten years, acid rain have been an important cause of concern because it continues to pollute large areas of our planet. Acid rain occurs (following the direction of the link) in the areas of important industrial emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx). The first time this problem

Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Caused by air pollution, acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil. Power plants use that coal and oil to produce the electricity we need to heat
