Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

Floyd Askew 3/19/13 CHEM 1211L Lab Report Introduction The purpose of this lab is to use volumetric analysis to determine the concentration of unknown substances. A sodium hydroxide solution is standardized to assist in finding the concentration of an acetic acid. An indicator must be used to pin point the equivalence point‚ the point in which 1 mole of a substance is equal to 1 mole of another. When that is found‚ we can determine the concentration.

Potentiometric Titration of Sodium Carbonate Otieno O. Victor University of Detroit Mercy Quantitative Analysis Lab CHM 3880 Fall 2011 Partner: Edwin Gay Abstract The PH at each point during the titration of sodium carbonate unknown sample was determined. An Unknown sample of Na2CO3 was titrated with a standard HCL solution. In addition to titration‚ the pH at each point of titration was measured using PH meter. The % of the unknown Na2CO3 was 25.83% Introduction1 The purpose of this experiment

of sodium hydroxide (NaOH) was determined by using a known amount of Potassium Hydrogen phthalate (KHP). The balanced chemical equation for the reaction is: KHC8H4O4(aq) + NaOH(aq) => H2O(l) + KNaC8H4O4(aq) (1) KHP was chosen as a good acid to standardize NaOH because it has high molecular weight and stable on drying. The standardized NaOH solution was then used to determined the percent composition of KHP in an unknown substance #47. Experimental Information Part 1: Standardization of

Appendix A We used a variety of data sources and methods to provide a comprehensive analysis of the U.S. fast food market. Through publicly available data‚ we thoroughly document and evaluate the menus and marketing practices of the nation’s largest fast food restaurants. Whenever possible‚ we used the same methods as our 2010 report‚ “Fast Food FACTS: Evaluation of the nutritional quality and marketing of fast food to youth‚”1 to measure changes over time. Our methods include analyzing
