Title: zinc reduction
Post by: rsixtyone on October 25, 2005, 04:44:20 PM

Will Silver, Cobalt, or Calcium would successfully reduce Zn⁺² ions?

None!? because the choices of those elements doesn't have a +2 oxidation state?

You need to look at a reduction potential table...

how can you read one of those table? ::)

When two reduction half-reactions are used to form a cell, the half-reaction with the higher reduction potential proceeds in the reduction direction whilst the half-reaction with the lower reduction potential proceeds in the oxidation direction.
