You want to “plate out” nickel metal from a nickel nitrate solution onto a piece of metal inserted into the solution. Should you use copper or zinc? Explain.
Interpretation Introduction
Interpretation:
The plating of nickel from nickel nitrate solution on a piece of metal is given. The metal used for the plating of nickel is to be determined.
Concept introduction:
The oxidation occurs on anode, while reduction occurs on cathode.
The metal used for plating of a metal is made up of the anode therefore it must have lower reduction potential.
To determine: The experiment that can determine if a reaction is spontaneous or not and the relationship between spontaneity and the final equilibrium position of a reaction.
Explanation of Solution
The plating out of nickel metal is done using zinc as an electrode.
The metal that has to be plated out is made up of the cathode, while the other metal is made up of the anode. The anode is the electrode that has a lower reduction potential as compared to the cathode.
The reduction potential of zinc and copper are
