Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness is often alloyed with aluminum. Magnesium is also used in racing car wheels called MAG wheels. Many car-manufacturing companies will use magnesium and aluminum because of the lightness of the metal. Both of these metals are reactive with acids. The most common acid in they react with is hydrochloric acid. In this lab‚ we collected a gas

Abstract: The purpose of this lab is to prepare phenylmagnesium bromide‚ a Grignard reagent‚ and react it with benzophenone to give triphenylmethanol. Once made‚ the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone‚ benzophenone. The result is an alkoxide that is then protonated to give the alcohol‚ triphenylmethanol. The purity of the final product will then be considered by melting point and IR spectroscopy. Final purified triphenylmethanol weighed 8.02 grams

Determination of Calcium ions in milk using titration. Background Calcium is a mineral which is essential to the human body. In fact 1.5% of the human body is made up of calcium‚ and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions‚ for example blood clotting. It also partakes in the regulation of the hearts rhythm. Lack of the crucial mineral can result in the build up of cadmium and lead‚ both of which are toxic. along

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

the test tube is like a light yellow but on the bottom of the test tube the yellow is darker. 3. Magnesium metal and hydrochloric acid solution Place one scoop of magnesium turnings into the test tube. Add hydrochloric acid slowly and observe the reaction. Next‚ place a burning splint near the mouth of the test tube to test for the presence of hydrogen gas. Observations when its put the magnesium metal and the hydrochloric acid solution it look like many bubbles Observacion: cuando se pone

this experiment was to synthesize the tertiary alcohol triphenylmethanol from a Grignard reagent‚ phenyl magnesium bromide. The Grignard reagent was synthesized from bromobenzene and magnesium and then reacted with benzophenone to produce triphenylmethanol. It was important that water be excluded from the reaction‚ in order to prevent the formation of benzene. The reaction of phenyl magnesium bromide and benzophenone was quenched with sulfuric acid‚ and an extraction was performed in order to separate
