that mixtures are Filtration and Evaporation. Filtration is the process of separating the solid from the liquid by using a porous filter. And Evaporation is the process of reducing the volume of a solution. The substances that separated are the sand and the salt. What is the purpose of adding water to the residue (the solid particles that remained on the filtering medium)? We add water to the residue so that we can easily separate the sand from the salt. And after the filtration the sand was left

Then 50 mL of distilled water had to be added and the mixture had to be stirred for one minute before being poured through the filtration apparatus into another preweighed beaker called “Beaker number 2”. Not all of the substance would be easy to get out of beaker 1 so it had to be rinsed with 5mL of water and then the remainder had to be poured through the filtration apparatus into beaker 2.

three years‚ his team was confident this latest iteration was a winner. For Vyas‚ general manager of the Filtration Unit of Applied Research Technologies (ART)‚ the request presented a major challenge. He recognized that his team had worked tirelessly to make this project a reality and strongly believed they were now headed in the right direction. But he also understood that the Filtration Unit’s track record of failure during this product’s development had hurt its credibility. If he supported

Electrophilic Aromatic Iodination of Vanillin Purpose: The purpose of this laboratory experiment is for an aromatic compound to undergo an electrophilic substitution reaction. To carry this out‚ our method combines sodium iodide and common bleach as the oxidizing agent in aqueous alcohol as the solvent.

up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order to create the powder form of aspirin‚ the process of crystallization was conducted and was run through vacuum filtration. After running through the help of an electronic instrument‚ the result that was achieved in this experiment was met due to the presence of esters in the graph in Figure 5; with a peak of 1297.89 at 1300-1100. There is also a match of 35.48 with

The Excretory System • Main functions of the excretory system are: o to concentrate wastes and expel them from the body o to regulate fluids and water within the body • Most metabolic wastes and toxins are dissolved in the body’s internal environment‚ so the maintenance of the body fluids is essential for keeping the body free of waste products enabling it to function properly. Excretion in Invertebrates and Non-mammaliam Vertebrates • Single celled organisms and simple multicellular

Diabetes Assignment This assignment will be looking at the pathophysiology of Type 1 diabetes‚ the effects this has upon Carol in terms of symptoms and how it may affect the developing embryo and foetus. What is Type 1 Diabetes? Diabetes type 1 is an organ specific autoimmune disease which develops in the pancreas and islet cell antibodies when the body’s immune system attacks and destroys insulin producing beta cells (Nelson-Piercy‚ 2005). This affects the metabolism of fats‚ proteins and

Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined that the unknown

Cholesterol is purified using a hot gravity filtration. Why must the beaker and filter paper be kept hot? • Hot gravity filtration is used to separate insoluble impurities from a hot solution. Both the beaker and the filter paper should be kept hot in order to stop the dissolved compounds crystallizing from solution during filtration‚ thus forming crystals on the
