Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

Although the world may disagree about many issues there is a commonality that continuously unites nations from all over the world‚ and it is a fundamental system in which the world cannot function without‚ the International System of Units (SI). The SI was established in 1960 by the 11th Conference of Weight and Measures; it began with 17 nations including the United States and today has become widely used among 51 nations (Historical). The SI is a metric system of units of measurement and is predominantly

Courtney Cubine 6/19/13 June 20‚ 2013 Separation of a Mixture of Solids Purpose: The purpose of this experiment was to help the student learn how to separate a mixture of multiple different solids and determine the percentage of each component of the mixture. Procedure: I started off by removing the iron using the magnet‚ and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron.

Rey Vincent P. Antonio Experiment 8: Quantitative Determination of Copper Concentration in Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the

Synthesis Procedure 1 -1.0 Introduction A Cobalt-Amine-Halide compound is synthesized from cobalt (II) chloride hexahydrate. An orange-tinted solid is produced and is considered to be unknown since the specific ligand amounts are unknown. By determining the percent composition of various elements and compounds in the unknown‚ its true identity can be predicted. Chloride‚ ammonia‚ and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns
