National 5 1. Sweets‚ such as pineapple cubes‚ contain the artificial flavouring methyl butanoate. a) To what family of compounds does methyl butanoate belong to? 1KU Methyl butanoate can be broken down to form an alkanol and an alkanoic acid. b) Name this type of reaction.1KU c) Draw the full structural formula for the alkanoic acid and the alcohol formed from the breakdown of methyl butanoate. 2PS 2. Ethanoic acid is more commonly known as vinegar. a) Draw

Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid

two indicators‚ as in the analysis of carbonate-bicarbonate mixture. The two methods involved in this experiment were the classical method and the potentiometric method. In classical method‚ the endpoints of the two indicators (phenolphthalein and methyl orange) were determined using titration method. In the potentiometric method‚ the progress of the titration was monitored using a pH meter. B. Introduction Sodium carbonate is an important industrial chemical. It is used in the manufacture

Faculty of Engineering University of Santo Tomas España‚ Manila February 27‚ 2013 Abstract The analyte used is the soda ash which is titrated with an HCl titrant‚ standardized by Na2CO3. The indicators used are phenolphthalein for basicity and methyl orange for acidity. The two volumes of the titrant are then used to calculate percent composition of soda ash analyte. At the end of the experiment‚ the calculated average percent by mass of Na2CO3 is 4.92% and the average percent by mass of NaHCO3
