    ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

    Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic

    The intent of this paper is to educate individuals about acid rain‚ define its chemical makeup‚ and describe its impact on the environment. Rain is an important part of all life; it is the source of water for almost everything. In some areas rain is actually a threat to life because of pollution from cars‚ factories‚ and power plants. This pollution releases gases into the atmosphere to create acid rain. Acid rain is rain‚ or any other form of precipitation that is uncharacteristically acidic

    N2O EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U

    Acid rain is a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen

    The Grignard Synthesis of 3-methyl-3-heptanol In this experiment‚ an example of an organometallic compound which has a carbon magnesium bond will be utilized to form a tertiary alcohol. Grignard reagents have been extremely useful in the synthesis of a large number of classes of organic functional groups. Although Grignard reagents are unstable and decompose in air and moisture‚ they can be prepared and used immediately with moderate difficulty in the undergraduate organic chemistry laboratory
