Jolyne Piet CHM-221L-02 Lab #2: Experimental Design Isolation of Sucrose: 3.01 g Panacetin were weighed in a 125-mL Erlenmeyer flask‚ and 51mL dichloromethane were added to partially dissolve the Panacetin. The insoluble portion was gravity filtered and air dried to yield 0.45 g of sucrose (15.0 % of original Panacetin). Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer

ISE Determination of Fluoride Content in Various Substances CHM 222 – A 4 / 20 / 2007 Introduction: The ion selective electrode used was made up of a silver / silver chloride reference electrode and a glass electrode. The pH of the electrochemical cell is determined by monitoring the electrical potential difference between the half-cells. The glass electrode is an ion selective electrode (ISE)‚ which only responds to the hydronium ion concentration / activity in a solution under a

CHM 4300/6938 Biomolecules Microbes in Gut Increase Fat Absorption You may think you have dinner all to yourself‚ but you’re actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie’s Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats‚ allowing the host organism to extract more calories from the same amount of food. Previous studies showed gut microbes aid in the

Are Aromatic Hydrocarbons Carcinogenic Aromatic hydrocarbons or arenes are hydrocarbons characterized by alternating double and single bonds between carbons. Benzene is the most common aromatic hydrocarbon‚ but there are some non-benzene based compounds called heteroarenes‚ where a carbon is replaced by an oxygen‚ nitrogen‚ or sulfur‚ that are also aromatic compounds. Aromatic hydrocarbons exist in our daily lives regardless if we recognize them or not. Aromatic hydrocarbons are ingested or
