Sodium sulfate

Experiment required: copper (II) sulfate hydrate, 2 crucibles, electronic mass balance, bunsen burner, iron ring, crucible tong, clay triangle, wire gauze, retort stand, 1. Individuals should wear goggles on and tied hair back before the experiment started. 2. The mass of an empty crucible cover was measured. 3. Approximately 2.00g of copper (II) sulfate hydrate samples was taken out and put into the crucible. 4. The mass of the crucible cover and copper (II) sulfate hydrate samples was…

Abstract For this experiment the amount of zinc in vitamin water had to be determined. To do this, three methods were applied. The first was by a calibration plot method, where zinc standards were prepared and from the absorbance of those standards a calibration curve was plotted, which in turn was used to determine the amount of zinc in vitamin water. The second method was standard addition. For this method, an un-spiked and spiked solution were prepared. The un-spiked solution only contained…

substances and finished products in a multitude of solvents. In the testing of the four starting substances for the soaps, the group found that all the substances were insoluble in water and hydrochloric acid. However, vegetable oil was soluble in sodium hydroxide whereas the rest of the substances were not. This proposes that the beginning substances for the soaps are non-polar organic materials, as shown on page 59 of the lab manual1. Then, they tested the four soaps and two detergents that…

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…

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…
