Experiment 5 COMMON ION EFFECT MALUBAY‚ Justin Damian PADRILLAN‚ Hazel Rose CD2‚ Group 5 Ms. Sarah Sibug 6 April 2013 ------------------------------------------------- ------------------------------------------------- I. ABSTRACT The common ion effect occurs when a given ion is added to an equilibrium mixture that already contains that ion‚ and the position of equilibrium shifts away from forming more of it. This paper is a follow-up of the experiment which aims to determine the common-ion effect

The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

THE 4 QUALITIES OF GOOD WATER by Dr. Robert O. Young There are many measurements of water‚ but the most important for determining the best water to drink are‚ the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking

In this experiment‚ we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask‚ we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out
