WebbK2Cr2O7 + 14HI = 2KI + 2CrI3 + 3I2 + 7H2O is a redox reaction where I is oxidized and Cr is reduced. HI is a reducing agent (i.e. it lost electrons) and K 2 Cr 2 O 7 is a oxidizing agent (i.e. it gained electrons). Enter a redox reaction equation to balance it and calculate the reducing and oxidizing agents.
