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
OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed
September 23rd, 2014 Matter & Qualitative Lab Report Purpose:- The purpose of the lab is to perform series of tests to determine the physical and chemical characteristics of several unknown powders, and then use that information to classify the unknown powders. Hypothesis:- I believe that by testing substances with various chemicals, for example, vinegar, iodine and that will help to find out what the substance is and what is it quality. Materials:- In order to perform this lab, you need:- • Litmus
Identifying inorganic compounds using qualitative analyses and chemical tests Jessica Vithayathil U84363206 CHM 2045L Section: 033 Aaron Clark October 13, 2016 Introduction Due to climate change during the turn of the 21st century and overall population growth, scientists have noticed greater amounts of negative impact on water sources (Barber, 2011). Waste Water Treatment Plants (WWTPs) have been identified as one of the root causes of stress for these water sources (Barber).

Monosaccharides are one group such as glucose. Disaccharides are two monosaccharides joined together such as sucrose. Polysaccharides are large chains of monosaccharides bonded together such as starch. Oligosaccharides are small chains of monosaccharides. This lab uses six different carbohydrates. Those carbohydrates are glucose, fructose, ribose, lactose, sucrose, and starch. Glucose, ribose, and fructose are all monosaccharides but fructose is a ketose rather than an aldose. Lactose and sucrose are disaccharides;
Introductory Chemistry 1110 Qualitative Analysis Using Precipitation Reactions Lab reports are due week of September 29 – October 3, 2014. Your lab report must contain the following information: Experimental data may be collected with other students in introductory chemistry labs. However, I understand that sharing information required for a lab report or unknown submission (including but not limited to word processing or spreadsheet files, calculations, graphs, conclusions and additional
distinction is often made in sociology between quantitative and qualitative research methods. Quantitative methods intend to measure social phenomena by using mathematical methods and statistical analysis. On the other hand, qualitative methods mean to collect rich, detailed data, allowing for an in-depth understanding of an individual. “It is often assumed that quantitative approaches draw on positivist ontologies whereas qualitative approaches are more associated with interpretive and critical paradigms
This quarter I had the opportunity to work in Dr. Greeson’s lab as one of her research assistants. Dr. Greeson studies community and social psychology primarily and her main focus of sexual assault is reflected in her studies and research. There are currently two directions of Dr.Greeson’s current research and both are at different places in the process of the research completion. One is that she works to evaluate the success of DePaul’s sexual assault prevention programs. This is evaluated through
DISCUSSION The experiment used qualitative analysis to determine two cations in an unknown solution. In Part A, identified either silver or lead that was interfused into the metal nitrate salts solution. In Part B, calcium or barium would appear. In Part C, another method of qualitative analysis was performed by cation flame tests. The various metal chloride solutions would be used to observed and recorded the colored flame of each species. The goal was to practice qualitative strategies to be able to
