You are given aqueous solutions of AgNO₃, Cu(NO₃)₂, Mg(NO₃)₂, Fe(NO₂)₃, Zn(NO₃)₂, and Ni(NO₃)₂. You also have available the free metal of each of the six cations. Using only these materials, can you suggest a chemical method for arranging the metals in order of increasing reducing power?

How to answer this question? and what is the answer to this question?

I am working on this question. Any chemistry help will be accepted.

Immerse each metal in the given solutions. If a precipitation takes place the given Metall is more inoble as the one in the solution.

For example a copper wire will coated with silver if immersed in silver nitrate.
In opposit a silver coin will not harmed by copper nitrate.
