Experiment 5 The Quantitative Determination of an Acid in Carbonated Beverages Thomas Canfield Kelly Caddell Chemistry 144B T.A. Brock Marvin 15 October 2012 Methods: Two sodas containing citric acid were investigated in this experiment. Each soda was titrated using one of the two experimental methods. These methods are the traditional titration and the modern titration. Carbonic acid was already removed from the soda by boiling it. Both of the two different titration methods

Experiment V02 An analysis of aspirin tablets Procedure a. Weigh accurately a definite number of aspirin tablets (two or three tablets weighing no more than 1.5 g) into a 250 cm3 conical flask. Initiate the hydrolysis of the aspirin by adding 25 cm3 of 1.0 M sodium hydroxide by pipette‚ diluting with approximately the same volume of distilled water. Warm the flask over a tripod and gauze for ten minutes to complete the hydrolysis. b. Cool the reaction mixture and transfer with washings to

BACKGROUND: Esterification is a reaction that combines an alcohol with an organic acid‚ with a water molecule is being taken out‚ and an ester is formed. A concentrated acid catalyst speeds up the esterification. In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ

Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

Henri Murphy Mr. Dietrich English 101 29 Aug 2014 Determination I have been in school for twelve years and seen many friends drop out.

How would earth be different if iron didn’t exist? What would we lose? how might it affect you? If we didn’t have iron we wouldn’t have a large portion of the earth’s core. Without the earth’s core we would have less gravity and everything would be lighter and atrophy would happen to our muscle and bone density. If there is less gravity the would drift away from earth leaving us with chaotic weather and chaotic tides. The core also creates a shield which helps with a variety of of things not happening
