DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

ASSIGNMENT QUESTION: ‘‘A Trend in Contemporary Time is the Increasing Need to Comprehend Basic Quantitative Methodology and its Language as a Tool for Decision Analysis’’ Prof J.A. Fabayo. Do You Agree? ANSWER: Background A person managing a production unit for instance‚ a factory‚ a farm or even a kitchen has to coordinate men‚ machines and money against several constraints like time‚ cost and space in order to achieve the organization’s objectives in an efficient and effective manner

INTRODUCTION TO QUALITATIVE AND QUANTITATIVE RESEARCH METHODS There are generally two kinds of research: qualitative and quantitative. For any research project the researcher needs to be clear about which type of research will provide the information required. The role of qualitative research is to tell you why; quantitative research tells you how many. The methods are quite different. Definition of Quantitative research? "There ’s no such thing as qualitative data. Everything is either 1

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:

lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette and burette. Then we had to perform three measurement

OUTLINE OF BASIC CRITIQUE STEPS (understanding quantitative research): Brink and Wood (1994)‚ and Burnes and Groves (1997)‚ similarly describe the steps for quantitative nursing research process and methods. The authors include not only the basic steps to conduct nursing studies‚ but also translating the studies into articles for publication. According to Burnes & Groves (1997)‚ and Hamric and Spross (1992)‚ the quantitative research method is used to describe or gain more information‚ test relationships

reflect the amount of DNA concentration available; higher quality DNA specimens generallyhave a higher concentration of DNA. Differences between the availability of specimens can also differ between these methods; feathers are highly available for analysis while blood and muscle would be scarce in comparison. Blood and muscle specimens would require cold storage in order to prevent DNA degradation‚ unlike feather samples which would most likely be degraded. The identification of gender in birds has

Experiment A Spectroscopic determination of Iron with Phenanthroline Unknown # 2 Mass of Mohr’s Salt: 0.2040 1. 5mL of 6M acetic acid was measured and transferred into a 100mL volumetric flask with a pipette and diluted to the mark. Concentration = [0.2040(±0.0001)g/100(±0.08)mL]*[(1mol/392.16g)/(1L/1000mL)] = 0.005202(±0.09382%) = 0.005202(±0.000005)mol/L 2. 10mL of the above stock solution was transferred to a 250 mL volumetric flask and diluted to the mark.
