Testing chemicals

[logosan]

So I acquired some chemicals, unfortunately though some bottles are not labeled, and I can't figure out which is which. So I'm wondering if there are tests I can conduct to know what solution is the developer, fixer , etc.... Also if there are tests to see if the chemicals are in good condition, because from the state of the bottles they look kinda old. Thanks in advance for any help.

For developer, you try to feel it, it should be soapy.
For stopbath, it is likely to be light yellow in colour.
For fixer, it should be colourless. And it have quite a strong smell. Drop a drop of it on unexposed film, you will find that the film base emulsion disappears after a while.
Hope that helps.

That helps tremendously, thanks.. any tests to insure the chemicals are in usable condition?

Stop & Fix will prob still be okay, I would ditch the dev and mix up a new batch.

on the topic of chemicals, how long can you keep a bottle of dev, stopper and fixer open?

thanks!

Now that you mention it frametology, the chemicals I aquired were not stored in a cold place, but the bathroom.. which is also a humid place if you take lots of hot showers.
