Write a balanced half-reaction for the reduction of CrO42–(aq) to Cr(OH)3(s) in a basic solution. a. CrO42–(aq) + 3 OH–(aq) + 3 e– -> Cr(OH)3(s) + 2 O2(g) b. CrO42–(aq) + 3 H+(aq) + 3 e– -> Cr(OH)3(s) c. CrO42–(aq) + 3 H+(aq) -> Cr(OH)3(s) + 2 e– d. CrO42–(aq) + 4 H2O(l) + 3 e– -> Cr(OH)3(s) + 5 OH–(aq) e. CrO42–(aq) + 3 OH–(aq) -> Cr(OH)3(s) + 2 O2(g)
