Re: Dichromate Shelf Life Mixed

But general rule of thumb for all solutions: a saturated solution, or just relatively strong, can be expected to keep better than a much diluted solution.


If you mix with distilled water the shelf life of dichromate solutions is
for all practical purposes as long as the dry chemical. I have some solutions
that are over 5-10 years old and still work perfectly.
