    I would dump everything, but if you insist on a test, if you add acid to Carbonate it fizzez and if you add acid to Sulfite it stinks.

    Thanks, Ron. Am I correct in assuming that the black liquid had to be the A solution? (pyrogallol, sodium bisulfite and KBr. It had about 6 years to oxidize in that half full jar.)

    Of course I'm going to dump all the old liquids. But I don't want to put any of the new solutions in a container which contained a different one. I'd get new jars first.

    Jim;

    If it is black, it is not the Carbonate or the Sulfite. These two chemicals in solution remain clear or water white but cloudy for their entire lives.

    Why al the fuss? Are the jars worth that much?
