    Ferric ammonium oxlate stability

    Anyone able to tell me how long a working solution of ferric ammonium oxalate is stable in a stoppered brown bottle. Making up 10 Gms in 25 mls of water is going to last me weeks rather than days at my rate of output!
    Thanks

    It should be ok for a few months if stored right. I keep mine on a dark cool shelf in my darkroom. It usually takes me a couple of months to use a 25ml batch.

    Not a real test, but I used one bottle for well over 12 months - brown glass bottle, kept tightly capped. Current bottle is over 8 months old, going strong.
