Verified step by step guidance

Understand the concept of reduction potential: Metals can cause ions to come out of solution based on their reduction potential. A metal with a lower reduction potential can reduce ions of a metal with a higher reduction potential.

Identify the reduction potential of Ni2+: Nickel ions (Ni2+) have a specific reduction potential, which you can find in a standard reduction potential table.

Compare reduction potentials: Look up the reduction potentials for each of the metals listed (Au, Sn, Mn, Ag, Cu) and compare them to the reduction potential of Ni2+.

Determine which metal can reduce Ni2+: The metal that has a lower reduction potential than Ni2+ can donate electrons to Ni2+, causing it to be reduced to solid Ni.

Select the appropriate metal: Based on the comparison, choose the metal with a lower reduction potential than Ni2+ to cause Ni2+ ions to come out of solution as solid Ni.
