Write the oxidation and reduction half-reactions for a silver-chromium voltaic cell. Identify the anode, cathode, and the direction of electron flow.

Ag+ + e-  Ag
Cr  Cr2+ + 2e- or Cr  Cr3+ + 3e- ????? Which is the correct equation for the chromium side of the reaction?
Anode: chromium
Cathode: silver
Electron flow: chromium to silver

What you have looks ok to me. Cr will go to Cr^3+.
