which four amino acids‚ histidine‚ lysine‚ glutamine‚ and glutamic acid‚ are identified based on their titration behavior. Solutions of each unknown amino acid are made and the change in pH upon adding small amounts of NaOH aliquots of a strong base are monitored. The amino acids are identified using the information represented by the titration curves. The titration curves include the following information: isoelectric points‚ pKas‚ buffering regions and the structures of the amino acids. The results

of Acetylsalicylic Acid Abstract Acetylsalicylic acid was prepared using salicylic acid and acetic anhydride. As a result‚ a white‚ powdery substance was formed (0.1931g‚ percent yield 91.30%) and was defined by melting point (124.5 – 134.5°C) and observation of color change with ferric chloride. Introduction Acetylsalicylic acid (aspirin) is one of the most popular analgesic drugs on the market today. It also acts as an antipyretic and anti-inflammatory drug. Salicylic acid itself was too acidic

The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear
