Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

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

Application of lactic acid bacteria There are four major categories for the current uses and applications of LAB: food‚ cosmetic‚ pharmaceutical‚ and chemical applications. In food industry Recent years the interest increased in using LAB by using bacteriocin-like inhibitory substances (BLIS) because of their potential use as a natural antimicrobial agent to enhance the food safety of food products and increase the nutritional values of the food. Foods that fermented by LAB such as cheese‚ kimchi

1.0 Aim The purpose of this experiment is to use Volumetric Analysis to determine the concentration of acetic acid in white vinegar. 2.0 Theory The concentration is a measurement of relative amounts of solute and solvent. There are many diverse ways of expressing concentration but the most accepted and widely used is molar concentration and regularly referred to as molarity which is defined in mole‚ the amount of solute dissolved in one litre of solution.

genetic information that can be highly useful in solving a crime. DNA is the basic unit of life. The molecule uses the arrangement of bases and forms into a double helix. This arrangement contains information and instruction for the development of the body. DNA defines each of our individual characteristics therefore making it very unique. The “arrangement of these bases in each DNA molecule is different for everyone except identical twins” (Wilson‚ Foreman &ump; Asplen‚ 1999) and this is the key to
