Commercial Aspirin Tablet Analysis Tuesday Evening Intro: The purpose of this lab was to analyze commercial aspirin tablets. To do so‚ the percent acetylsalicyclic acid (active ingredient) in tablets using acid-base titration was determined‚ the percent acetylsalicyclic acid in tablets by formation of a colored iron(III)-salicylate complex was determined using spectrometry‚ and then the percents from each process was compared. Acetylsalicylic acid is produced when salicylic acid and acetic

Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is

Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

article concludes that businesses using commercial television to promote their products will achieve the greatest advertising success by sponsoring only highly- rated programs—preferably‚ programs resembling the highly-rated non-commercial programs on public channels. Supporting this claim is a recent study indicating that many programs judged by viewers to be high in quality appeared on noncommercial networks‚ and that the most popular shows on commercial television are typically sponsored

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at

Commercials has a great influence in our day to day lives. All commercials‚ basically attempt to persuade the people to buy the products. Commercials let people know about the new products the company (ex. Apple) launches and reminds the customer that their product is superior to the competitor’s product.
