BS1003 – Organic Chemistry Practical 1 Laboratory Report Name: Tristan Chan Yew Kit, U1640436J (T8) Effects of Dichloromethane(DCM) in Extraction of Caffeine from Tea Leaves Purpose To investigate the ability for Dichloromethane(DCM), a moderately polar organic solvent, to extract aqueous caffeine molecules, originating from Tea Leaves suspended in water. Introduction Caffeine, defined chemically as 1,3,7-trimethylxanthine (C8H10N4O2), is an alkaloid that can be found in tea leaves, coffee and many

Several efforts have been made over recent years to maintain a safe and clean environment. However, environmental pollution is getting worst and poses a major threat to the Earth. Environmental pollution is “the contamination of the physical and biological components of the Earth to such an extent that normal environmental processes are adversely affected” (Kemp, 1998, p. 129). There are five known pollution which is in the form of air, water, land, noise and light (refer to Figure 1 in Appendix

Description of Ladbroke Grove Rail Crash The Ladbroke Grove rail crash is termed as one the worst rail accidents that have ever occurred in Britain (Kletz. 2002). The accident occurred on the 5th of March in 1999 at the Ladbroke Grove. On this day, 5th of March 1999, at exactly 08:06 British Summer Time, a Thames Trains service departed from Paddington station, platform nine and veered off to Bedwyn railway station in Wiltshire. The Thames Train (whose headcode was 1K20) was the type of a 3-car

The Hinton Rail collision of 1986 is one of Canada’s worst rail disasters, occurring just on the outskirts of the Rocky Mountains in Alberta. This mass disaster was the result of a head-on high speed collision of a VIA rail Super Continental passenger train and a Canadian National freight train, leaving behind the remanence of torn apart passenger cars, shattered glass, burning chemical fumes and piles of scattered debris (Ferllini, 2012, p.170). Such a scene required the assistance of forensic anthropologists

Grishma Patel Chloroplast Pigments and Colored Light Absorption Summary The purpose of executing this lab was to see how different wavelengths and colors of light are absorbed by chloroplast pigments. The goal was to see the variations of light dependant reactions of photosynthesis based on different types of light. Spinach was used by grinding it with acetone and acquire the thylakoids used in the experiment. DCIP was used in this experiment as the oxidizing agent that will turn blue to clear when

source of salicylic acid is methyl salicylate present in wintergreen oil. Salicylic acid is obtained by hydrolysing methyl salicylate, an ester under basic conditions. This synthesis takes place through a 2-step organic reaction. It is also referred to as saponification. Saponification is a special type of hydrolysis which converts an ester into an alcohol and a carboxylic acid. The first step (1) of the hydrolysis, involves the addition of NaOH to methyl salicylate. The reaction is then put under

but until then there are a few natural remedies you can use to reduce the pain. Wintergreen Oil Wintergreen green oil is used as a topical treatment for treating pain caused by injuries, chronic aches and infections. The essential oil contains methyl salicylate, which is the same ingredient that is found in aspirin. This ingredient makes it a natural pain reliever. The best
