The purpose of Module 11A was to test for the presence or absence of a particular set of functional groups through the use of wet chemical tests. In this manner‚ Unknown A which was a colorless solution‚ was first tested with 2‚4-DNP which after mixing for a few seconds formed a bright yellow precipitate. Although this confirms the presence of either a ketone or aldehyde group‚ one simple chemical test does not completely specify the presence or absence of other functional groups. Therefore‚ a second

NTRODUCTION Often in the study of microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well
