Section 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 assignment 3.4 Part F of the Chemistry 11 course. I was unable to do this experiment because I do not have access to an appropriate facility that is designed for chemistry experiments, appropriate safety equipment, or a qualified instructor.
Refer to the reaction of iron nails with a copper solution assignment in Module 3, Section assignment 3.4 Part F of the Chemistry 11 course. * Step A: Put on your lab coat (apron) and goggles.
* Step B: Determine the mass of a clean and dry 250 mL beaker. * Step C: Obtain a sample of CuCl2(s) (about 8 grams) from your instructor and add it to the beaker. Determine the accurate total mass of the beaker and the CuCl2(s).
Caution – Copper (II) chloride is poisonous. Clean up any spills immediately. Get help from your instructor. Wash your hands after using it.
* Step D: Dissolve the CuCl2(s) in about 50 mL of distilled water. * Step E:
1) Use the sand paper to clean the surface of the nails. 2) Determine the mass of the nails.
3) Place the nails in the CuCl2(aq) solution so that they are totally covered by the solution. 4) Allow the nails to sit for at least 20 minutes – the longer the better. Record your observations over the 20 minute period. * Step F:
1) While holding each nail with the tongs, use a wash bottle, and a stirring rod if necessary, to get all the copper that is stuck on the nail into the beaker. It is important to remove as much copper as...
