Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Lactic Acid Bacteria Amanda Perry Many persons are oblivious to the fact that when they consume certain delicious food products like yogurt‚ buttermilk or cheese‚ they are actually eating live bacterial biomass which has acidified the milk content and contains a mixture of bacterial slime layers. Perhaps it is a blessing that most people are unaware because when most hear the word ‘bacteria‚’ their first thought is of a microscopic unicellular organism that causes various types of diseases especially

This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

How Acetylsalicylic Acid was Discovered Acetylsalicylic Acid in its earliest form was a powder for the bark and leaves of the willow tree. Hippocrates‚ who lived sometime between 460 B.C. and 377 B.C‚ founded it. This “Miracle Drug” that was able to relieve pains was later looked into with further detail by Johann Buchner. He isolated a tiny amount of bitter tasting yellow‚ need- like crystals‚ and called salicin. By 1829 French Chemist Henri Leroux had improved the extraction procedure to
