    Lewis Acids and BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid

    Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

    PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the
