Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

PROCEDURE: 1. Cut 18 potato cores from the same potato using a knife and place them onto the lab bench. Using a scalpel and ruler (calibrated in millimeters) cut the cores into 50 mm lengths‚ with care taken to ensure no potato peel being left on them. The cutting will be to an accuracy of 1 millimeter 2. Mass each potato core using the mass balance. The mass will be to an accuracy of 0.01 grams. 3. Place the potato cores in a Ziploc bag. Label the bag and place in the tub – they will be refrigerated

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff
