TITLE: Determination of Riboflavin by using UV-Vis spectrophotometry. ABSTRACT: The amount of Riboflavin in various brand of children multivitamins was determine by using UV-Vis spectroscopy instrument‚ the series of standard of riboflavin was prepared in order to determine the amount of the riboflavin in the sample of children multivitamins. The maximum amount of riboflavin was found in the Champs multivitamin that contains 0.1155 mg followed by Chewies 0.1131 mg and Scott’s 0.0672 mg. OBJECTIVES:

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

The global market for biosurfactants is expected to reach USD 2‚308.8 million by 2020‚ according to a new study by Grand View Research‚ Inc. Escalating consumer preference towards the use of bio-based products‚ particularly in Europe and North America is expected to increase biosurfactant penetration. In addition‚ stringent regulatory policies are further expected to augment the biosurfactant demand over the next six years. Methyl Ester Sulfonate (MES) was the largest consumed biosurfactant‚ accounting

Experiment 1: Synthesis of Isopentyl Acetate via Fischer Esterification Introduction: Isopentyl acetate‚ banana oil‚ is a naturally occurring compound that has a very distinct and recognizable odor. It is most commonly found in bananas but also can be found in other organisms. The purpose of this lab was to synthesize the ester isopentyl acetate via an acid catalyzed esterification (Fischer Esterification) of acetic acid with isopentyl alcohol. Emil Fischer and Arthur Speier were the pioneers
