It is prepared by roasting powdered chromite with potash and limestone, treating the cinder with a hot potassium sulfate solution and leaching.
Alternatively, it may be prepared by the reaction of potassium dichromate and potassium hydroxide.

What is difference between K2Cr2O7 and K2Cr2O4?
K2Cr2O4 is not true, must be K2CrO4. Differences are; K2Cr2O7: Potasium dichromate is red-orange crystalline solid. K2CrO4: Potasium chromate is yellow odorless powder.
What is the oxidation number of Cr in K2Cr2O4?
K2Cr2O4 Using oxygen at '-2' as the standard. Then the oxygen moiety is 4 x -2 = -8 Since K is only +1, and there are 2 x K , then this moiety is '+2' The overall charge on the molecule is zero. So we make a sum 2 + 2Cr - 8 = 0 2Cr = 8 - 2 = 6 Cr = +3 ( THe oxidation No. of Cr'.
