The reactions between acids and metals

A 1 cm length of magnesium ribbon was placed into 10cm of acid in a 1. 00M solution, at room temperature. Each experiment was timed in seconds for the metal to be displaced. The results of the experiment are shown in the table below: Acid Time (Seconds) Sulphuric 50. 42 Hydrochloric 81. 11 Nitric 372…. View Article

The time allocated

To find to what extent certain factors speed up the rate of the first reaction involved with making ‘Epsom Salts. There are four possible factors that could be used to increase the rate of this reaction involving Magnesium and Sulphuric acid to produce Epsom salts. Preliminary Research: Magnisium: Scientific definition and uses: Magnisium is a… View Article

The mass would be measured

Introduction: Magnesium is a metal which need get rid of two electrons; oxygen is a gas at room temperature and it needs two electrons and magnesium oxide is ionic compound because when they join up they are ions and both elements have an opposite charge which creates electrostatic attraction between them creating a very strong… View Article

Acids and varying concentrations

Hydrochloric acid 1M hydrochloric acid 1. 5M hydrochloric acid 2M hydrochloric acid Results of the reaction between sulphuric acid and magnesium: time/s Columns 2, 3, 4 and 5 show the volume of gas (in cm3) produced when different concentrations of sulphuric acid are used in the reaction with magnesium. 0. 5M sulphuric acid 1M sulphuric… View Article

Magnesium Diboride

Magnesium diboride (MgB2) is a metal with some very special properties. At a temperature of 39 K1 (about -234i?? Centigrade), it becomes what is known as a superconductor. You may have heard that as metals decrease in temperature, their resistance decreases. How ever, in some materials, the pattern of a gradual decrease in resistance is… View Article

Law of Constant Composition Lab

Purpose: To determine the percent magnesium by mass in magnesium oxide and to observe if the percentage composition is constant by comparing class results. Hypothesis/Prediction: The percent composition by mass of magnesium in magnesium oxide will not change significantly with each group that conducted the experiment. The composition of each substance should stay the same… View Article

Grignard Synthesis

Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Procedure: Refer to the microscale lab in pages 124-130 (15.1 and 15.2) in Modern Projects… View Article

Empirical Formula Lab Report

INTRODUCTION John Dalton’s atomic theory states that elements combine in simple numerical ratios to form compounds. A compound, no matter how it is formed, always contains the same elements in the same proportion by weight. The law of mass conservation states that mass can neither be created nor destroyed. In this experiment, the mass of… View Article
