Acid

Acid rain is a rain that is more acidic (has more hydrogen ions) compared to normal rain and it has serious negative effects to nature and people. It is a mixture of wet and dry depositon that contain high amounts of nitric and sulfuric acids (see Figure 1). These gases come from electric generation, factories, forest fires, burning fossil fuels and acid rain forms when these gases react with water, oxygen and air. Wet deposition happens when acid chemicals fall to the ground in a rain or snow…

and even cars (webprojects.edu, 1). Acid rain is something humans should be concerned about in the twenty-first century due to our advancements in technology. The majority of the United States suffer from acid rain and as a result, many communities are impacted making water unsuitable for drinking and the environment around them damaged. Despite the fact that many people think acid rain isn’t a big threat to the world, damages caused by acid rain can be…

Aims of Experiment 1. To extract benzoic acid from the toluene-benzoic acid mixture, using oxidation-reduction reaction (chemical properties) and difference of solubility (physical properties) –Expt. 1 2. To learn how to recrystallize the solid organic compounds well for getting more purified compounds –Expt. 2 3. To find which differences between raw product and recrystallized product are observed. –Expt. 2 4. To determine melting point range of organic compounds with digital melting point…

titration of a strong base with a weak acid, including its equivalence point and half-equivalence point. The following equation demonstrates the dynamic equilibrium achieved when using a weak acid: The Ka value of a weak acid can be found experimentally using a pH meter along with the concept of equivalence point when titrating an acid and a base. One half of the weak acid has been titrated at the half-equivalence point, meaning that the concentration of weak acid [HA] and its conjugate base…

Saponification is a method used in treating a neutral fat with alkali, breaking it down to glycerol and fatty acids. The saponification value or saponification number is the amount of alkali needed to saponify the given quantity of fat or oil, expressed as mg potassium hydroxide to saponify 1 g of the sample. In this experiment, the researchers used chemicals such as ethanol, hydrochloric acid (HCl), potassium hydroxide (KOH) and phenolphthalein indicator. Laboratory Apparatuses and Equipment…

What are the Uric Acid Rich Foods? – Uric acid is a chemical that is formed in the body when the body starts breaking down and this causes purine (purine) to grow. There are some food and drinks such as beer, mackerel, grind, beans, anchovies and dry beans. It is a special acid that travels through the kidneys in the blood and travels through kidneys and urine/urine and thus increases some conflicts. If a number of uric acid increases in the blood then the cause of hyperuricemia becomes. In…

A: Background Information Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton (hydrogen…

Introduction Ascorbic acid is a form of vitamin C that is used by the body as a means of promoting healing of cuts and wounds, as well as boosting the immune system and as such aiding in the fight against infections. Ascorbic acid does not occur naturally and is formed by carrying out a variety of chemical reactions on corn syrup. The chemical formula for ascorbic acid is C6H8O6 and is similar to glucose which has a formula of C6H1206, this closeness in structure allows most animals (excluding…

Acid, below-normal pH, causes many problems in our world today—from drinks to teeth, from pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in…

Ecology Research Laboratory are the authors of Acid Rain and its Ecological Consequences, a review addressing the issue of acid rain precipitation. The article hypothesizes, “Acid rain is one of the most serious environmental problems emerged due to air pollution” (Agrawal & Singh, 2008). It was assumed that humans have harnessed and utilized different natural resources for their individual benefits from the onset of civilization to the present day. In turn, acid rain has become a major…
