Purifying Potassium dichromate
Here at CAI we are reclaiming the elements from used COD tubes (Ag, Hg and Cr.)
Once we have precipitated potassium dichromate, anybody have a suggestion for a simple purification procedure?

Yes, RC. K2Cr2O7 isn't highly soluble in cold water but very soluble in hot water. Ideal for recrystallisation purposes...
