Assignment 3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module 3‚ Section

STOICHIOMETRY The reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power •30 ml

especially mines which contain pyrite. Oxidation of sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding

Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2
