Joscely Garris Professor Vinh Hoang CHEM 1151L – 254 25 October 2013 Preparation of Viscous Solution This report discusses an experiment to study the relationship of solute/solvent and the calculations involved to measure the concentration of the solution. The first experiment to take place is the preparation of a salad dressing using xanthan gum solution‚ water and oil. Commonly used as a food thickening agent‚ Xanthan gum is a large molecule composed of several saccharides linked together

The Melting Pot The myth of the melting pot was created by a man named J. Hector St. John de Crèvecoeur. His idea was that immigrants from all over the world would come together to create a new society. A new race‚ religion and way of life would come from this society. The myth is widely known today and is often related to the United States. America is known to be a melting pot because it is a society made up from people of different race‚ culture and beliefs. The myth of the melting pot implies

48% yield). The crude acetaminophen was then recrystallized in a solvent of water and methanol over heat resulting in 0.082 grams (39.61% yield) of pure acetaminophen. Melting points of both crude and pure acetaminophen were taken‚ and found to be 165.9 - 170.9°C and 168.2 - 171.5°C‚ respectively. The literature melting point of acetaminophen is 169.5 – 171.0°C‚ indicating that our final product was pure. Introduction The synthesis of acetaminophen involves the attraction

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions‚ creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride‚ acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly‚ an excess of methanol will form methyl salicylate‚ which is also an analgesic. In this experiment‚ we shall use the former reaction to prepare aspirin. Salicylic

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour
