6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

Determining substances contained in a mixture using qualitative analysis Introduction: The purpose of this lab was to determine the substances contained in a random mixture using qualitative analysis. Qualitative analysis is the analysis of a substance in order to ascertain the nature of its chemical constituents (Qualitative analysis). The substances that could be found were iron‚ cinnamon‚ corn starch‚ baby powder‚ copper‚ and strontium. A magnetism test was used to determine whether iron or

considering that the photoreduction period took a couple extra days due to lack of sunlight‚ loss of product can be attributed to this since we only could get 2.11g/3.0g of benzpinacol from the start of the lab. And since benzpinacol was the limiting reagent‚ before starting part 2 of the lab this already set us up for some loss in % yield. Also when we transferred our product from the filtration funnel to the watch glass there was product loss because many of the crystals were stuck in the flask

Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material’s initial treatment and the microstructures that are formed from different processes‚ an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used‚ along with a Hardness tester‚ a grinding and polishing process‚ and a micrograph

Qualitative Methods And analysis * . Quantitative research is used widely in social sciences such as sociology‚ anthropology‚ and political science. Research in mathematical sciences such as physics is also ’quantitative’ by definition‚ though this use of the term differs in context. In the social sciences‚ the term relates to empirical methods‚ originating in both philosophical positivism and the history of statistics‚ which contrast qualitative research methods. Qualitative

Qualitative Analysis Qualitative is where the results give a colour that you have to match up to a colour chart‚ or have you have done to see if it is positive or negative with a description of what a positive reaction should look like. This test is less reliable as some colour or positive reaction look similar to each other or the same but by adding different chemicals. An example of qualitative would be a pH test as the result gives you a colour and then you have to match it up to the pH scale

Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Write up for Qualitative Analysis 1. Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand. Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing
