Electrochemical Cells: Line Notation

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 Sn²⁺ (aq) is reduced to Sn (s) . Assume all aqueous solutions have a concentration of 1 mol/L.

Answer 1

Pt(s) | Cr²⁺ aq, 1M) | Cr³⁺(aq, 1M) || Sn²⁺(aq, 1M) | Sn(s)

Use a single line | to separate different phases and different aqueous species. Use a double line || to indicate a salt bridge.
