Many chromate (CrO4) salts are insoluble, and most have brilliant colors that have led to their being used as pigments. Choose the correct net ionic equation for the reaction of Co³+ with a chromate ion. Co³+ (aq) + CrO4 (aq) → CoC-O4(s) 2Co³+ (aq) + 3CrO4 (aq) → Co₂ (CrO4)3 (8) 2Co³+ (aq) + CrO4 (aq) → Co₂ (C-04)3(S) 2Co³+ (aq) + 3CrO4 (aq) → Co₂ (CrO4)3 (29)
