esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006). Figure1 is drawn using Chem Sketch software. a) b) Figure 1: Typical Fischer esterification reaction (a) in comparison to the specific esterification reaction used in this lab (b) The reaction can also be categorized in terms of

One of the greatest things about vitamins is that they can be taken in both pill and liquid form. Experts in nutrition consider liquid vitamins to be a remarkable breakthrough in the domain. This is one of the reasons which may explain the lately outburst of liquid supplement advertising. But what makes liquid vitamins better than their pill equivalents? First and foremost‚ it is a matter of absorption. The liquids are chewable tablets which are being absorbed quicker by the body. It is estimated

Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and to test for contaminates such as NaCl and KCl. These tests helps us to determine the properties of the drilling fluid and so what can be done to make the mud perform more efficiently.

preparation and stability of liquid Paraffin Emulsion Abstract This study describes the preparation of a Liquid Paraffin Emulsion from Paraffin oil‚ Emulsifying agents and Distilled water. This report will also evaluate the stability of the Liquid Paraffin Emulsion depending on how the emulsion is produced and whether using different methods of mixing will produce a more stable Paraffin Emulsion. Introduction An emulsion is a mixture of two or more liquids that are normally not formed
