Chemistry Homework

Question

Write the cell notation for an electrochemical cell consisting of an anode where Cr2+(aq) is oxidized to Cr3+(aq) at a platinum electrode and a cathode where Fe3+(aq) is reduced to Fe2+(aq) at a platinum electrode. Assume all aqueous solutions have a concentration of 1 mol/L and gases have a pressure of 1 bar.

 

I am having trouble solving this homework problem

Answer 1

See my answer to your previous question.

Answer 2

I would do it this way:

Pt, Cr²⁺ | Cr³⁺ (1M) || Fe²⁺, Fe³⁺ (1M) | Pt
