Acid Rain Research Paper What is acid rain? Rain is one of the most dire and essential needs for a thriving ecosystem‚ and to sustain human‚ animal‚ and plant life. The water provided by the water cycle‚ the event causing rain‚ is required to keep all life on Earth alive. Rain‚ although naturally acidic‚ seems to have been increasing at a rapid rate due to many reasons. Some of these many reasons include‚ pollution. Pollution from homes‚ factories‚ power stations‚ cars‚ and many more

The Effectiveness of Phosphoric Acid on Meat Chapter I. Introduction A. Background Of The Study This experiment was performed to find out if the acidity in Coca Cola could dissolve meat. The testing was done by placing pieces of pork‚ chicken breast and salmon into bowls filled with Coca Cola‚ and observing meat for 5 days. Coca Cola is a popular carbonated beverage that is sold in more than 200 countries. Also known as Coke‚ it can be purchased from vending machines‚ department stores and

Conjugated linoleic acid‚ is a form of linoleic acid‚ an omega-6 fatty acid important to human health (Wang and Jones‚ 2004). The CLA is formed by the bacteria in rumen of certain ruminants but not for humans. It is obtained by humans from dietary sources such as beef‚ lamb and dairy products including milk and cheese (Wang and Jones‚ 2004). CLA is an antioxidant‚ anti-carcinogenic‚ anti-diabetogenic‚ anti-atherosclerotic‚ anti-catabolite as well as an immune system enhancer (Belury‚ 2002). Health

Trans-Sahara trade refer to the trade between North Africa and Western Sudan across the Sahara desert. The trade requires travel across the Sahara to reach Sub-Saharan Africa from the North Africa Coast‚ Europe or the Levant. While the trade existed from

Acid rain is a rain or any other form of precipitation that is unusually acidic‚ i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals‚ and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides 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

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be
