Lab Determining the Empirical Formula of Magnesium Oxide

Abstract In the Lab Determining the Empirical Formula of Magnesium Oxide, students set out to find if there is a true 1:1 ratio in the empirical formula of MgO. This was determined by burning the Magnesium until a white smoke started to protrude. This showed the reaction of Oxygen combining with Magnesium to form Magnesium Oxide. This was then measured again and turned out to be slightly heavier than the measurement before. This added weight is Oxygen, forming the combustion of Magnesium Oxide. The formula...

Pre-Lab Discussion An empirical formula is a formula for a chemical compound found by direct laboratory examination. Laboratory procedures allow the chemist to find the simplest whole number ratio of elements within the compound. In order to find the true molecular formula, the chemist also needs to know the compound’s molecular mass. The general procedure is to use laboratory techniques to determine the mass of each element in the compound. In this lab, we will react a known quantity of magnesium...

Copper metal will re­form, and the solid aluminum will dissolve and make aluminum sulfate. This is another oxidation­reduction reaction. In this case, copper (II) is gaining electrons from either magnesium or aluminum to make copper metal. Magnesium or aluminum loses electrons; they are oxidized. 6. Dissolve Excess Magnesium or...
