This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
Data Table: Oxidation-Reduction | | Reactions | Mg in Na2SO4 → | | Zn in MgSO4 → | | Pb in Zn(NO3)2 → | | Pb in FeCl3 → | | Fe in CuSO4 → | |
Questions
A. Based on your observations make an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too.
B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does nickel fit into your activity series?
The chemical reactions for the preceding question B are: Cu (s) + NiCl2 (aq) à no reaction
Fe (s) + NiCl2 (aq) à 2 Ni (s) + Fe Cl2 (aq)
C. Suppose you inserted a piece of an unknown metal into a solution of zinc (II) nitrate and observed no reaction. Then if you inserted the unknown piece of the metal into the solution of iron (III) chloride a deposit formed on the bottom of the well in the well plate. Where does the unknown metal fit into your activity series?
