Question
Write the oxidation and reduction half-reactions for a silver-chromium voltaic cell. (Use the lowest possible coefficients. Include states-of-matter at 1 atm and 25°C in your answer.)
Answers
You add the states. You don't say acid or base solution.
Ag ==> Ag^+ + e
3e + CrO4^2 + 8H+- ==> Cr^3+ + 4H2O
Ag ==> Ag^+ + e
3e + CrO4^2 + 8H+- ==> Cr^3+ + 4H2O
