citric acid stop

anyone know the capacity and/or approximate shelf life of a 15 g/liter
working solution ?

Have you any litmus paper? If not see
www.microessentiallab.com . Dan

should you really bother? The stuff is so cheap (buy bulk) you don't need to
store it. Just make yourself fresh stop bath and after your print session,
just discard it.

Never re-use stop bath.

Always dilute from the bottle and discard.

I appreciate the comments, but would anyone care to address my actual
question? I haul all my used chemicals into town to dispose of them,
and I really dont need several extra liters or gallons a week if I can
avoid it. Is there no published info on citric stop? What about
Ilford's? I have a Ph meter that I've used in the past, but it still
doesnt answer my basic question.

Dilute and discard down the drain. No harm will be done.

Ilford's info for Ilfostop is at:

I'm puzzled why stop bath would require special disposal.
Citric acid isn't toxic and a small amount of developer
carried over is hard to get excited about. I understand
being concerned about silver in spent fixer and possibly
some developers, but I wouldn't have thought that stop
bath would be any problem.

You know so much about my personal drain situation that I feel very
fortunate for your informative, authoritative and detailed replies.

If your drain is an ordinary household drain (and you have not told us
otherwise) there is no reason to worry. If your situation is different,
it is up to YOU to tell US. RIGHT?

I didnt ask you anything about my drain. You decided to change the
question to suit your answer
