To understanding the metabolism of alcohol‚ we should know that what is alcohol‚ how is it affect human body. Alcohol is being considered one of the most commonly used drugs because it has adverse impacts on human’s health through how it’s metabolized. Alcohol is a compound of hydrogen‚ carbon and oxygen‚ which can be combined in many different ways. The commonest as known as ethyl ethanol‚ which is a specific alcohol compound (C2H5OH) and formed from the fermentation of yeast‚ sugars

Acid-Base Titration Pre-Lab Discussion In the chemistry laboratory‚ it is sometimes necessary to experimentally determine the concentration of an acid solution or a base solution. A procedure for making this kind of determination is called an acid-base titration. In this procedure‚ a solution of known concentration‚ called the standard solution‚ is used to neutralize a precisely measured volume of the solution of unknown concentration to which one or two drops of an appropriate acid-base

and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used to soften water‚ which makes it useful in soaps and laundry detergents. By chelating the metals in hard water‚ it lets these cleaners produce foam and work better without need for water softening devices. Citric acid is the active ingredient in some bathroom

Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)
