    increase per milligram after its expiration date? Overtime, the concentration of acid in a low dose aspirin tablet increases, as the concentration of acid in a high dose aspirin tablet decreases. However, due to various experimental errors, the claim is not a strong and compelling one. What is assumed to have happened is that both low dose aspirin tablets and high dose aspirin tablets increase in concentration of acid as the expiration is surpassed. Four different tablets (two new and two expired):

    The acid-balance must be regulated with a range of 7.35 and 7.45 in order for the body to function normally. A pH of below 7.35 is considered acidic and a pH of above 7.45 is considered alkaline or basic. Body acids exist in two forms; volatile and nonvolatile acids. Volatile acids can be eliminated as CO2, usually known as carbonic acid, which is a weak acid. Nonvolatile acids can be eliminated by the kidneys, example are sulfuric and phosphoric. These acids are strong compared to volatile acids

    1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous

    What Is Acid Rain? In common parlance, acid rain is just what the words man – rainfall that is acidic in nature. However, in scientific terms it has a winder connotation. So, what is acid rain? Any way by which acid falls out of the atmosphere is considered to be acid rain. It can be dry or wet. Acidic gases or particles are referred to as dry deposition, whereas acid rain, snow and fog constitute the wet deposition. Be it particles, snow or gases, they can be termed as acidic if only they have

    an organic acid. An inorganic acid or mineral acid is an acid derived from one or more inorganic compounds. The reason that organic acids are weaker than mineral acids is that organic acids do not separate completely in water, whereas strong mineral acids do separate completely in water. Organic acids do not react with metals. Harsh mineral acids on the other hand react forcefully with metals. Inorganic acids are derived from inorganic compounds and mineral sources, while organic acids have a biological

    Topic: Acids and Bases. Introduction Acids are chemical agents that, when mixed with water, release hydrogen ions. Acids have a pH of under 7 on the pH scale.(Williams, 2016) An acid produces a sour taste, like Vinegar, and gives off a strong smell, that burns the human nose. Acids are often very sticky, and react strongly with metals, and create a chemical reaction to form H2. (Guch, 2003) A Base is the complete opposite of an Acid, and describes a substance that is above 7 on the pH scale.

    Experiment 5 The Quantitative Determination of an Acid in Carbonated Beverages Thomas Canfield Kelly Caddell Chemistry 144B T.A. Brock Marvin 15 October 2012 Methods: Two sodas containing citric acid were investigated in this experiment. Each soda was titrated using one of the two experimental methods. These methods are the traditional titration and the modern titration. Carbonic acid was already removed from the soda by boiling it. Both of the two different titration methods

    soft-water aquatic environments, that are exposed to acid precipitation (Neville & Campell, 1988). This acidification of the surface water is caused by acid rain. Acid rain or otherwise known as acid deposition is a term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that comes down from the atmosphere in wet or dry forms. These forms include rain, snow, fog, hail or even dust that can be acidic. Acid rain is caused by when sulfur dioxide (SO2) and

    students went to the Conodoguinet Creek in Acri Meadow Park to test it for pollution. The two main causes of water pollution are eutrophication and acid rain. Eutrophication is excessive richness of nutrients in a body of water, frequently due to runoff from land, which causes a dense growth of plant life and death of animal life from lack of oxygen. Acid rain is mainly caused by a chemical reaction that starts when compounds such as sulfur and nitrogen are released into the air. It can come in many
