WebCr (OH) 3, this hydroxide is an amphoteric compound. Chromium 3+ ion and zinc amalgam Cr 3+ can be reduced to Cr 2+ by zinc amalgam. Zinc amalgam is used in clemmensen reduction to reduce aldehyde and ketone to alkanes. Chromium +6 oxidation state WebAcicular chromium dioxide was first synthesized in 1956 by Norman L. Cox, a chemist at E.I. DuPont, by decomposing chromium trioxide in the presence of water at a temperature of 800 K (527 °C; 980 °F) and a pressure of 200 MPa. The balanced equation for the hydrothermal synthesis is: 3 CrO 3 + Cr 2 O 3 → 5 CrO 2 + O 2
