Wang Experiment #4 Recrystallization of Pure Phthalic Acid‚ Benzoic Acid and Napthalene Introduction Recrystallization is a important method in purifying organic compounds which are solid. It is an effective method that is important to be familiar with that is essential in the industrial chemical world. This experiment will allow students to be familiarized with the technique of recrystallization by working with phtalic acid‚ benzoic acid and naphthalene from appropriate organic solvents. Experimental

Therefore‚ the experiment was performed to conduct quality control analysis on two commercial products to determine the amount of acid or base active in these two products and then compare the results to those of the manufacture. This was done through the preparation of standardized acid solution and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used.

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

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is

Imagine you are doing your weekly shopping‚ pushing your cart down the canned vegetable aisle‚ and there are no labels on the cans. Just varying sizes of aluminum cans. How would know the difference between a brand named canned of peas versus the store brand? How would you even know it was canned peas? Labeling is a key element in product identification and marketing. During this essay‚ I will guide you through the process of identifying the key aspects of your custom label design and the execution

non-essential amino acids‚ amino acid remodeling‚ and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen. However‚ the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus‚ the potentially toxic nitrogen of amino acids is eliminated via transaminations‚ deamination‚ and urea formation; the carbon skeletons are generally conserved as carbohydrate‚ via gluconeogenesis‚ or as fatty acid via fatty acid synthesis pathways

The Central Role of the Citric Acid Cycle 3 processes play central roles in aerobic metabolism. The citric acid cycle. Electron transport . Oxidative phosphorylation. Metabolism consists of: Catabolism: the oxidative breakdown of nutrients. Anabolism: the reductive synthesis of biomolecules. • The citric acid cycle is amphibolic
