Hi guys,
Is there a quick-and-dirty way of telling if a solution of potassium bromide is still good?
How about sodium or potassium carbonate?
All of these are said to keep indefinitely, but it would be nice if I could somehow test them from time to time, to make sure they're still OK before risking a film.
Thank you.
