variety of specialty chemical products. The company acquired Octel Associates‚ a tetraethyl lead (TEL) producer for its capacity to produce bromine. Though Octel used the chemical to make the additives‚ Great lakes used them in other products. The focus was on the TEL"gold mine" that Octel provided. The company was willing‚ in order to get the bromine-producing capability‚ to take on the last years of production of lead additives as well as an ethical and public relation challenge. This

Experiment 8: Identification of an Adulterated Herb The purpose of this lab is to analyze the volatile oils of some herbs through TLC testing and then identify the adulterant in a sample. Unfortunately‚ we ran out of time to complete the lab; however‚ we were able to get through most of it‚ and were only missing the adulterant. The first step to identify our unknown samples was to create TLC plates that should results with each known compound and 95% hexane: 5% ethyl acetate‚ 90% hexane: 10%

ELECTRONEGATIVITY This page explains what electronegativity is‚ and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegativity in an organic chemistry context‚ you will find a link at the bottom of this page. What is electronegativity Definition Electronegativity is a measure of the tendency of an atom to attract a bonding pair

electrolysis to work‚ the ions must be free to move. Ions are free to move when an ionic substance is dissolved in water or when melted. For example‚ if electricity is passed through molten lead bromide‚ the lead bromide is broken down to form lead and bromine. Electrolysis Here is what happens during electrolysis: - Positively charged ions move to the negative electrode during electrolysis. They receive electrons and are reduced. - Negatively charged ions move to the positive electrode during
