Selective precipitation of the Barium Magnesium Group Chem 112-004 Abstract The purpose of this experiment is to separate and identify the cations of Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+ using differences in solubility and confirming test to identify the unknown solution used in this experiment. In this experiment the methodology used by the group is to perform the tests for both the unknown and the cations (Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+) using the known as a control for comparison and identification

quantity of magnesium metal to form chloride product. We then mass the final product and subtract to find the mass of chlorine in the product. Once we know the masses of elements in the compounds‚ we can convert to moles and determine the simplest whole number mole ratio. Objective The objective of this lab is to determine the empirical formula of magnesium chloride. Methodology 1. Measure the mass of an evaporating dish with its watch glass lid. 2. Obtain a strip of magnesium metal approximately

Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.

Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate

Should fluorine be added to water? Introduction: Fluoride is a natural mineral and a chemical‚ which is a compound of fluorine that is the most commonly used in water sources. However not only for that‚ it also has a various number of other uses in example: making molten metals flow‚ and burning materials etc. as it is an extremely reactive and highly toxic element‚ so when it comes to adding fluoride to public water‚ that’s when mankind is faced with some extremely

Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2 (g) This equation shows that when magnesium is combined with

reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen. The magnesium displaces the
