Mabel M. Kimble September 21‚ 2014 Chemistry 234 Recrystallization of Benzoic Acid ABSTRACT The recrystallization of Benzoic Acid was performed to fully master the ability to purify a solid compound. This form of purification technique is especially important in chemical identification‚ where the melting point of the compound is taken to confirm its purity. In order to perform recrystallization a solubility test much be completed. Four solvents (95% Ethanol‚ Petroleum Ether‚ Acetone and distilled

fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although shop-bought vinegar usually measures 2.4 www.wisegeek.com/what-is-vinegar.htm fig 1 In this study we will determine the amount of acid in a vinegar sample by using titration‚ a common technique in chemistry a typical shop brought vinegar has an acid percentage of 5% see fig 1. A titration is a technique where a solution of known

The reactivity series is the known series of how metals should react. It places Calcium as the most reactive (of the metals being tested in this experiment)‚ followed by Magnesium‚ Aluminium‚ Zinc‚ Iron‚ Tin and finally‚ as the least reactive (of the metals being tested in this experiment)‚ Copper. However‚ the results this experiment produced did not follow this trend. If the metal that produces the most hydrogen gas is considered the most reactive‚ in this experiment magnesium was most reactive

Heart rate investigation Research statement: To investigate‚ how diabetes affect a person’s heart rate during physical exercise. Background information: Heart rate : Heart rate is the number of time a persons heartbeats per unit of time‚ usually measured in BPM (beats per minute). Heart rate is measured by finding the pulse on body‚ usually taken from carotid artery‚ which supplies blood to the head and the neck and radial artery‚ which Is located on your wrist below your thumb

MANUFACTURE OF SULPHURIC ACID IN INDUSTRY 1. Contact process produces more than 90% of the world’s sulphuric acid. 2. The raw materials used for the manufacture of sulphuric aced are sulphur‚ air and water. 3. The Contact process consists of three stages. a) Production of suphur dioxide b) Conversion of sulphur dioxide to sulphur trioxide. c) Production fo sulphuric acid 4. Stage I: Production of sulphur dioxide a) Sulphur is burnt in air to produce sulphur dioxide. S(s) + O2 (g)→SO (g) b) Burning

Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2.

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of
