rainfall is slightly acidic because carbon dioxide in the atmosphere dissolves in the raindrops to produce hydrogen ions. Yet‚ normal rainfall is not considered acid rain. Acid rain is a form of air pollution in which airborne acids produced by electric utility plants and other sources fall to Earth in distant regions. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels

Running Head: Factors Affecting Citric Acid Production by Aspergillus niger Factors Affecting Citric Acid Production by Aspergillus niger Ong Chia Swing‚ Student. Nilai University 1. Introduction Citric acid is a natural preservative or conservative that is used to add an acidic‚ sour taste to foods and beverages. In the context of biochemistry‚ the conjugate base of citric acid which is the citrate plays an important role as an intermediate in the citric acid cycle which occurs in the metabolism

Acid Reflux or Gastroesophageal Reflux Disease (GERD) is caused by stomach acid rise towards the esophagus and cause pain in the solar plexus or a burning sensation in the chest. The cause of acid reflux (GERD) is the proper functioning of the lower esophageal sphincter (LES). LES is a circle of muscle at the bottom of the esophagus. LES serves as the automatic door opens when food or drink down to the stomach. After the food came in‚ the LES will be shut down to prevent the existing food and acid

Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

Acidity’s effects on Fruit Browning Aim: To test whether the acidity of the surface area of an apple has an effect on the rate of enzymatic browning over 70 minutes. Hypothesis: the more acidic the surface area the longer it takes for the fruit to oxidise. Variables: Independent: acidity of surface area of the apple Dependent: the progression of melanin (brown pigment) after 70 minutes Controlled/fixed: time of day‚ knife used to cut fruit‚ portion of fruit‚ environment

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult

First of which involves removing all of the flesh from the hide‚ once this is complete the hide goes into a solution known as the pickling processes. Once to this stage there are several products that may be used in order to complete a pickled fur. There are three main components to creating a pickling solution; these consist of sulfuric acid‚ non-iodized salt‚
