[answerhappygod]

When a metal is inserted into an ion solution, a redox reaction
may occur and the metal dissolves.

In which of the cases below will such a reaction occur? We assume
that we have standard conditions.

Use the voltage series (standard reduction potentials) to find the
solution to the task (see appendix) in Canvas.

Tip: For HNO3 solution, use the half-cell reaction for NO3- in acid
solution (i.e. with H+).
