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.

03/07/12 Quantitative research techniques used in Sociology Devon D.E. Francis Definition Quantitative research consists of those studies in which the data concerned can be analyzed in terms of numbers; Research can also be qualitative‚ that is‚ it can describe events‚ persons and so forth scientifically without the use of numerical data. Quantitative research is based more directly on its original plans and its results are more readily analyzed and interpreted. It is more open and responsive

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

Assess the position that in sociological research quantitative research methods are superior to qualitative research methods. Sociologists have a number of different types of research that can be used to acquire data. They can be traced back to Max Weber (1864) regarded as the founder of interpretivism‚ was opposed to the idea that human behavior is exactly quantifiable. Human behavior is based on the idea that social interaction is surrounded by consciousness action and unpredictability (emotions

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse

Australia has gone from a highly centralized wage determination system to a mainly decentralized one. There has been a move away from accords and awards to enterprise bargaining‚ through the 96 Workplace Relations Act. Recent policies include changes to unfair dismissal claims and the 2005 workplace reforms package. Throughout the 20th century‚ Australia has maintained a system of tribunals to make decisions about wage and non wage outcomes and to help resolve industrial disputes. Institutional

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

Complexometric Determination of Water Hardness. Abstract: Using complexometric method of calculating water hardness‚ an EDTA solution was made and calculated to be around .00209M. This EDTA solution was then used to titrate a water sample with unknown hardness. The sample used was sample #18. The hardness of the sample was calculated to be 180505 ppm. This is within normal levels for the Mesa area. Introduction: This experiment focuses on titration with EDTA. Titration

Many people will believe that ambitions are often achieved with the individual’s’ constant and continuous positive desire to achieve a goal‚ but it is truly the determination of one’s self towards a certain goal that allows them to achieve the success they intend. Through the inspirational story of Lance Armstrong‚ determination was significantly portrayed as the main motive that has driven him to overcome obstacles‚ both physically and mentally. With his previous achievement of overcoming an aggressive

Distinction between Quantitative and Qualitative Research Research can be defined as search for Knowledge with an open mind to establish novel facts‚ solve new or existing problems‚ prove new ideas or develop new theories. Quantitative and qualitative research is two methods of research. Quantitative Research deals with analyzing the subject and gathering measurable data. While Qualitative research deals with gathering of mainly verbal data rather than measurements. Gathered data is then analyzed
