Experiment 1 Name: Sanzhar Kerimbek 20140930 General Chemistry Laboratory 1 Fall Semester 2014 Co-worker: Byungsoo Kim 20140831 Date: 27.09.2014 Title:Volumetric analysis Introduction The concept of volumetric analysis is a part of chemical analysis and is performed foremost with the volumetric chemical glassware (i.e. Erlenmeyer flasks, burets, pipets, test tubes etc.). The aim is to find out the concentration of one substance by reacting it in aqueous solution with the substance with…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. FePO4 is also known as Iron (III) phosphate. Iron (III) phosphate is an inorganic compound. Most of the FeP04 has the structure of α-quartz which is α-FePO4. It has a tetrahedral molecular geometry. α-FePO4 is present at pretty low degree Celsius. It is also a transition metal as it is in the d-block in the periodic table. It can be studied at many different temperature which range from 294K to…

2. Materials and Methods: 2.1. Materials: Natural red, propidium iodide (PI), acridine orange and phosphate-buffered saline (PBS) were obtained from Sigma-Aldrich (St.Louis, MO). May–Grunwald–Giemsa stain was procured from Merck (Darmstadt, Germany). Fetal calf serum, Dulbecco's Modified Eagle Medium (DEMEM) and RPMI 1640 were bought from GIBCO/Life Technologies Inc. (Gaithersburg, MD). 2.2. Isolation and Proliferation of MSCs Bone marrow derived MSCs were isolated as described previously…

Accuracy and Precision Lab Report By Connor MacFarland 10.23.2016 IBC 1 Question What is the difference between accuracy and precision and how can we demonstrate the difference? MATERIALS Pencil Notebook Paper 100 mL Graduated Cylinder 1 Gallon of water Ruler Unmarked Plastic Container 3 different kinds of Rocks of different sizes Triple Beam Balance PROCEDURE Estimating Lengths Procedure A piece of notebook paper was torn into 8 rectangles Without a ruler, a line was drawn which…

Claim, Evidence and Reasoning Graphic Organizer Question: Are Fat and Soap Different Substances? Claim: Fat and soap are different substances. Evidence (from your data) Solubility - Fat was soluble in oil. Soap was not soluble in oil. Fat was not soluble in water. Soap was soluble in water. Reasoning (why does the above piece of evidence support your claim?) The above piece of evidence supports my claim because it proves that in the same substance (H2O), fat and soap have different…

Measuring the mass of Iron in an iron sulphate tablet using REDOX titration Aim The aim of this experiment is to determine the mass of iron present in one iron sulphate tablet using REDOX titration under acidic conditions. Safety H2SO4: This is an irritant which may cause burns on skin and eyes; therefore care must be taken when handling this chemical. Protective gear (gloves, lab coat and safety goggles) must be worn at all times. If it comes in contact with skin or eyes, it should be…

reaction is Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…

In this experiment, solid magnesium was conducted in a chemical reaction with hydrochloric acid solution. The three objectives include: measuring the gas production of a chemical reaction by a pressure change, determining the mass of the hydrogen gas produced in the reaction, and determining the effectiveness of the procedure by calculating the percent yield. In order to complete these objectives, a flask containing the magnesium ribbon was completely submerged into a large beaker filled with…

Once the solution was stirred, the cap was placed on the reaction vessel, which was put into the microwave for heating. Next, 40mL of 3M sodium hydroxide was chilled in an ice bath, and then the extraction apparatus was constructed. Once the microwave was done, the vessel was rinsed with 5mL of water, which was poured into the separatory funnel. Then cold sodium hydroxide was then added portion wise to the separatory funnel and the funnel was swirled. Next, 10mL of dichloromethane was added to…

Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…
