WebMar 1, 2024 · In detail, an initial 1000 ppm Cr (VI) stock solution was prepared by dissolving 934.0 mg K 2 CrO 4 in 2% v/v nitric acid water solution in a 250 mL volumetric flask. A second 10 ppm Cr (VI) stock solution was obtained by diluting 1 mL of the first stock solution with 2% v/v nitric acid in a in 100 mL volumetric flask. WebThe most common oxidation states for Cr are 0, +3 and +6. Chromium is most commonly found in the +3 state, which is fortunate since the +3 state is considered benign as opposed to the +6 that is toxic. At Inorganic Ventures we note the oxidation state of chromium in a given CRM by writing Cr +3 or Cr +6.
