Chromium possible charges
WebMar 1, 2024 · Chromium ions are found in nature in two stable oxidation states: Cr(III) and Cr(VI). In aquifers, Cr(VI) is thermodynamically favored under oxidizing conditions and is highly soluble in water. In the absence of ligands other than OH- and H 2 O, HCrO 4 − and CrO 4 2− oxyanions are the most stable Cr(VI) species in groundwaters [ 1 ]. WebMetals which have multiple possible charges need Roman Numerals in their compound names to specify their current charge. For the following metals, indicate which ones …
