The purpose of this lab was for students to familiarize and perfect the simple distillation method to produce 4-Methylcyclohexene and to gain experience using an IR spectroscopy to characterize the product of the reaction in favor of equilibrium. B. Results and Discussion: C. Experimental: 24 mL of 4-methylcyclohexanol‚ 5mL of phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer.

Experiment 28: The reaction of Butanols with Hydrobromic Acid Pre-lab Objective: The objective of this experiment is to synthesize 1-bromobutane and 2-bromobutane with different catalyst:substrate ratios to determine which ratio is the most economically favorable. Discussion: In this experiment‚ 1-butanol or 2-butanol will be converted to the corresponding alkyl bromide with HBR‚ while using sulfuric acid as a catalyst. The sulfuric acid will accelerate the chemical reaction with being consumed

Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of the benzidine residue and shuttling of macrocycle in to the biphenol station of the Rotaxane. This was supported by NOESY 1H NMR that showed a shift in the peaks in retrospect to

10.1 COMMON ACIDS and ALKALIS in DAILY LIFE A. ACIDS 1) In our daily life‚ there are many foods‚ drinks and flavourings that taste sour. e.g. yoghurt’ lemons and vinegar. 2) They taste sour because they contain acids‚ which give the sour taste. e.g. Yoghurt contains lactic acid. Lemons contain citric acid. Vinegar contains ethanoic acid. 3) Many household cleaners and personal care products also contain acids. e.g. Toilet bowl cleaners contain hydrochloric acid. Some body lotions

reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C

Exploring the acid content of Pepsi products Lab performed: February 27‚ 2012‚ March 12‚ 2012‚ and March 19‚ 2012 Purpose: The purpose of this experiment was to discover the unknown concentration of acid in six different Pepsi products; Pepsi‚ Diet Pepsi‚ Dr. Pepper‚ Diet Dr. Pepper‚ Pepsi Wild Cherry‚ and Pepsi Max. Titrations find the point at which equal moles of a known concentration react with equal moles of an unknown concentration giving the equivalence point. Also‚ the
