Group 5 2D-Medical Technology Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT The experiment was executed in order to purify compounds through recrystallization. Recrystallization is the primary used operation for purifying solid organic compounds that differ in solubility at different temperature. It is a process of dissolving

A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride

Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the

Writing Short Reports What makes a good report? Reports are essentially a management tool. Even the most capable managers rely on other people to collect information for them. You may be surprised that a variety of documents qualify as reports. The word report covers everything from preprinted forms to brief‚ informal letters and memos to three-volume manuscripts. The goal of developing a report is to make information as clear and convenient as possible. Good reports have three things in common:
