WebJan 6, 2024 · (f) Cr in BaCrO₄. Where Ba = +2, O = -2 and let the oxidation number of Cr = c +2 + c + (-2×4) = 0 +2+c-8 = 0. c - 6 = 0. c = 6. Therefore the oxidation number of Cr = +6 It can be synthesized by reacting barium hydroxide or barium chloride with potassium chromate. Alternatively, it can be created by the interaction of barium chloride with sodium chromate. The precipitate is then washed, filtered, and dried.
