When a piece of metal A is placed in a solution containing ions of metal B, metal B plates out on the piece of A.

Which metal is being oxidized?

Which metal would be the cathode in a voltaic cell with these two metals?

If bubbles of H2 form when B is placed in acid, will H2 bubbles form if metal A is placed in acid? Why or why not?

7. In biology, the roles of transition metal ions can be broadly grouped into two classifications: redoxchemistry (catalysis, electron transfer, etc.) and acid-base chemistry (catalysis, structural, etc.). (a) List three metal ions that commonly participate in biological redox chemistry, and give examplesof how they participate. (b) Compare this list to metal ions commonly participating in acid-base chemistry. Discuss the overlapof these two groups of metal ions. (e.g., why are some used for one of these functions and not for theother?)...

Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au3+ solution. The item itself serves as the cathode, at which the Au3+ ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit. What mass of gold is produced when 10.2...
