Chromium is a member of group 6, of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. Many Cr(0) complexes are known. Bis(benzene)chromium and chromium hexacarbonyl are highlights in organochromium chemistry. WebChromium (III) oxides are only slightly water soluble, therefore concentrations in natural waters are limited. Cr 3+ ions are rarely present at pH values over 5, because hydrated chromium oxide (Cr (OH) 3) is hardly water soluble. Chromium (VI) compounds are stable under aerobic conditions, but are reduced to chromium (III) compounds under ...
