Reactions in which Chromium(III) iodide is involved

  • 2Cr + 3I2 -> 2CrI3
  • 2CrI2 + I2 "500^oC"--> 2CrI3
  • 4CrI3 + 3O2 "200^oC"--> 2Cr2O3 + 6I2
  • {M}{X}3 + 3{R}OH -> {M}(OH)3"|v" + 3{R}{X} , where M = Al Cr Fe Ti La; X = Cl F Br I; R = Li Na K Rb Cs NH4
  • {M}2O3 + 6H{X} = 2{M}{X}3 + 3H2O , where M = Fe Al Cr La Sc Y; X = F Cl Br I (NO3)
