Another chemical query (shelf life)

My suggestion would be to "waste" a film on shots that you wouldn't be bothered if you lost....dev, stop and fix in the ilford chems and see what you get. (possibly cross process a quid agfa film)

Similarly do a test for the paper developer (if you ahve access to wet printing)

The other chems...no idea really tbh...perhaps google and see what they would have been used for and possibly experiment a bit.

From what I can remember - going back many years - acetic acid (basically vinegar) and sodium metabisulphite were/are used in home made stop and fixing solutions. Hydrogen Peroxide is an oxidiser and had some arcane applications in film development. I can't read the label on the small bottle at the front.

I have no idea of any of these are still usable, but they're 20 years old and have been opened. I'd just get rid of them. There are plenty of commercial developers/fixers on the market, and these are all cheap chemicals if you want to experiment with making your own. I'm sure someone with a lot more knowledge and experience of this sort of thing will come along and advise though!
 
i'd check the clearing time for the fixer ,and then either use or throw ,try the paper dev and you'ill know if its any good,and get rid of the ilfosol ,,,and if you've got any torpedos that need powering up ,,,,,,,,,,,,,,,,,:D
 
Glacial acetic acid gets its name from its high freezing point (52 degrees F)- so it should be stored at a reasonable temperature. It's the working part of a conventional stop bath, highly diluted with water. It has the characteristic smell of vinegar, unlike the citric acid used in odourless stop baths. I prefer acetic acid, because pickled onions don't go mouldy, and lemons do - indicating that acetic acid lasts longer withour mould. The glacial form is highly corrosive (so immediate wash if it gets on you) and also highly inflammable.

Sodium metabisulphite (Thanks - I couldn't make out the label) is generally used as an additive to make fixer acidic. It can also be used as a preservative for pyrogallol.

Hydrogen peroxide is used as a hypo eliminator; but an interesting side effect is that an acidic solution (or vapours from same) can fog sensitive materials.
 
Hydrogen peroxide is fairly unstable so I wouldn't be surprised if that had reduced entirely to water.
