I just re-read my chemist's message, and found that the conclusion I
came to by reasoning my way through a logical sequence, he actually
said straight out to start with: "I wouldn't think there would be any
difference between sodium and potassium
metabisulfites at the same molar concentration." So maybe I should just
read my mail more carefully and give my brain a rest. Any chemists
disagree with this, please say so, and support your answer. Thanks,
