Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

Chemistry Lab Report Purpose The purpose of this lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette

Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in

Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate the bacteria. The different

respiratory diseases or viral infections and people who have weakened immune systems are at greater risk. Pneumonia bacteria are present in some healthy throats. When body defenses are weakened in some way‚ by illness‚ old age‚ malnutrition‚ general debility or impaired immunity‚ the bacterial can multiply and cause serious damage. Usually‚ when a person’s resistance is lowered‚ bacteria work their way into the lungs and inflame the air sacs. The tissue part of a lobe of the lung‚ an entire lobe‚ or
