Dear All,
I would like to post here a version of my original question from APUG as it seems no one amongst that group of people has come across my conundrum.
I would like to make a more concentrated stock of Ansco 130 by using only 50% of the water. It is possible to mix it and all chemicals do dissolve, as I have tested this. My question is if such a concentrated stock should have a higher, no different, or shorter shelf-life.
I realise that it is claimed Ansco 130 has a very long stock solution life and the working solution lasts well too. Perhaps any chemists here would know if the concentrated version would be much different in terms of storage. Could concentrating it have any other impact on its performance when diluted again?
Many thanks,
Rafal
PS. I have another question about any experiences (good or bad) of using it replenished over a longer period of time, but I guess I should make a separate thread for it some time later on.
